It is for offside. Offside calls were so egregiously bad it was painful to watch. Any time a defense got burned badly, the flag would go up.

Early 2000's someone watched an entire world cup and found that 25% of offside calls were obviously wrong.

I just rewatched the US v Germany match from 1998, and Kobi Jones was called offside on a breakaway when he was onside by 4 yards when the ball was kicked.

Also, goal line and maybe handball seems to be handled pretty well.
