That paragraph is being used out of context it's for a foul committed on an 'inactive' offside player.

In order for that paragraph to apply Schar needs to be having no impact on play which he clearly is.
How is it out of context?
"a player in an offside position is moving towards the ball with the intention of playing the ball and is fouled before playing or attempting to play the ball, or challenging an opponent for the ball, the foul is penalised as it has occurred before the offside offence"
It gives the exact context and says it's a foul.
