OK, but you're attributing a position he has taken at some point in the past and trying to apply it to all future actions. Offside cares about where the players are at the moment the ball is played. The clause you're fixating on can only apply to an attacker if the ball is played towards him while he is off the pitch and he then comes back on in order to become active.
At no point in the video you posted is a player off the FOP at the point a ball is played forward - which suggests you are still fundamentally misunderstanding the way offside works and trying to apply offside law across multiple different points in time. You're asking complicated questions without the required understanding of the basics of timing and positioning for offside. Because if you had that understanding, you'd see that the clip you posted isn't relevant to this discussion.
