I suggest the guy wasn't stupid but knew exactly what he was doing, whether he was covered by someone with a gun or not.
We have lot of bears here in Canada, and here's some good advice I saw recently on a local paper although it doesn't cover polar bears.

Here's a momma black bear at our house with a cub, "bluff-charging" to warn me off (I was safely above her).

I agree. When I lived in Churchill, Manitoba I had a lot of polar bear encounters both planned and unplanned. What a lot of people don’t realize is that polar bears are fairly docile and live in a world of almost complete silence. They are usually deterred by little more than a loud vocalization or aggressive display. Of the operators that offer walking safaris out of Churchill none has ever had to destroy a polar bear and only every couple of years did we ever hear about a guide having to resort to the use of a bear banger (blank) to discourage a persistent bear. When incidents with polar bears do occur it tends to get over-sensationalized but most people living within polar bear range are infinitely more concerned about barren land grizzly bears where the ranges overlap. The bear in the video displayed typical behaviour. When encountering something previously untested polar bears tend to approach very cautiously, testing little by little to see if it is a potential meal. They don’t pounce on everything like they do with a familiar food source.
