I'm one of those. I'm right eye dominant, but look through the viewfinder with my left eye because it's more comfortable to me. Some articles on the interweb confuse the importance of eye dominance. Think about it. Dominance matters more when both eyes are kept open - e.g. when both of my eyes are open during archery, my right eye takes dominance and I shoot with a right-handed bow. If I was right eye dominant and left handed, shooting with a left-handed bow then this would be cross dominance and I could experience a degree of parallax.
In photography, this just isn't an issue because you keep one eye closed or shielded from within the viewfinder. It doesn't matter which eye you use. Because it's the only eye used, it doesn't matter if it's dominant or not. Dominance or non-dominance isn't a designation of stronger or weaker. Your optometrist can tell you which eye is stronger or weaker as a matter of how well you can read each letter on an eye chart.
There are exceptions to everything, of course. The responses from people in my thread reveal that some of the action sports photographers in this forum actually keep both eyes open and use the right eye on the viewfinder while the left eye track the subject. But of course, the right eye might not even be their dominant eye in their cases.
Boils down to what is comfortable and what works. Using your eye dominance isn't going to give you any better accuracy.
I'm actually "Centrally" dominant, which as a competitive rifle shooter, and former pistol shooter (no pistols anymore for us plebs in the UK) is a PITA, since I need to have a blinder when using a "Diopter", or aperture, sight, since with both eyes open I end up seeing the foresight with the left eye, and losing it completely from the right. It also makes shooting a shotgun very difficult, again I keep using my left eye half the time. I have also done a lot of bare bow archery and what is odd is as someone who is very right handed normally I can shoot the bow with either hand. Well when I was doing it every day I was about 95% with my left hand. I could put arrows in the center of the target, but not deliberately off center. At the time I worked at a holiday center where I ran "shooting" activities including archery and clay pigeon. When working with a group of four, when you only have four bows, it's much easier to pick up one of the spare left handed bows to do the demonstrations
I am an NRA (GB) Rifle Instructor and when working with novices will always try to get them you ignore handedness and go with eye dominance whenever possible. This was especially true of the ones with the rifle who try to put the left eye behind the scope on my .308 when I was coaching at the NRA's open days at Bisley. If they don't it ends in tears. I did have one shooter who although using right hand/right eye ignored everything I told them, and got their eye right up to the scope, and so scoped themselves, and they were not happy that I was more worried about keeping the blood off the rifle, than about them bleeding
When shooting with optical sights I can happily use my right eye through the scope, and independently watch the wind flags with my left. I guess because of the very different views that each eye is receiving. I am though using a 20× scope on my .308 F-TR rifle out to 1000x and 36× on the smallbore BR at 25x and 50m. At airshows I pretty much do the same when tracking aircraft. It makes it a lot easier to catch two aircraft crossing in opposition, although it does pretty much force a pan that goes right to left. The biggest issue I have is that usually with the RAF's Red Arrows it's the left to right aircraft that passes in front. Because it is much better to keep both eyes open whenever possible in shooting I just automatically tend to do the same with a camera these days. Oddly I started with photography way before serious shooting and initially always closed the left eye. As the shooting had me keep the eye open it gradually transfered to the camera too.
