Why does covering the can make it safer?

Water under normal pressure conditions will not exceed 212 degrees (the
boiling point). The water prevents the contents from getting too hot and
exploding the can.

I understand that part. I just question why Brian claims that the can has
to be completely submerged.

Much cross posting snipped
Only thing I can think of is even cooking of the contents. If the can is
out of the water, it will be exposed to steam at 212, but no higher. I
don't see how else the contents would be affected. Am I missing something?
