YouTube activity means exactly what "activity" is. Someone logged on and did something, whether uploaded a vid, liked one, created a playlist, etc. Given the already known, they liked a video. I don't believe would they post a video a week before its due date, only a couple hours / possibly a day earlier so that it completes processing.
