So why does HP play a role in the recommendation to get a bypass system? I can see rpm being the big driving factor.

It is due to more heat generated in higher HP engines which will cause the coolant to get so hot it becomes steam and that is what it corrects. It allows the coolant to flow and it never flashes over to steam due to the choke point. This issue can also happen on stock trucks that pull heavy. You will read of these folks burning down #6 and this issue can create that problem.
