No, you don't know what you're talking about. I have done this in AP/CW many times over. Bears waste their Run on turn 1 because of Bad AI so this is not a threat. And on turn 1 it's just silly to move 3, because you must only move 2 and attack with Lounge.
So let me get this right you try to kill multiple stacks of slow melee units with 1 royal snake all the time and you are successful at doing it?.....Youtube or it didn't happen.
