What is the purpose of quitting right before the game ends?

Continuing the discussion from Leaving game when seeing defeat or victory:

@JeffreyKaplan

Fun fact: you don’t actually get into a match faster when skipping the end of round flow (victory poses, POTG, cards, stats etc.). You don’t get entered into the matchmaking queue until your previous match resolves completely. Most people leave at “Victory/Defeat” because they think they are “speeding up” getting into the next match.

He doesn’t mention anything about it being exclusive to comp and my experience with quick play tells me that it isn’t exclusive either.
