No it doesn't depend on anything, because you're just plain wrong. Just because 2 in-game leaders who are both the best of best can talk about specific rounds and strats doesn't mean the average pro remembers all of them, and even if they remember it's a completely different thing to remember the key take-aways of those rounds and apply them in a meaningful fashion in a heated competitive setting.
Antistratting is a part of the game, but it's a completely different thing to antistrat 1 team vs 2 teams. Karrigan can remember the things against Astralis because he specifically prepped against them because they were Fazes number 1 rival at the time. Of course you're gonna remember that shit a week from now on. Do you really think he would've done the same thing to 4 different teams and still dedicate as much time and remember things as clearly? Of course not. It's just simple mathematics really.
