I know I'm just a stupid Yank, but has there been any explanation of which part of the offside rule Sigurdsson violated?

Offside position
It is not an offence to be in an offside position.
A player is in an offside position if:
- any part of the head, body or feet is in the opponents’ half (excluding the halfway line) and
- any part of the head, body or feet is nearer to the opponents’ goal line than both the ball and the second-last opponent
- The hands and arms of all players, including the goalkeepers, are not considered.
A player is not in an offside position if level with the:
- second-last opponent or
- last two opponents
Offside offence
A player in an offside position at the moment the ball is played or touched* by a team-mate is only penalised on becoming involved in active play by:
- interfering with play by playing or touching a ball passed or touched by a team-mate or
- interfering with an opponent by:
- preventing an opponent from playing or being able to play the ball by clearly obstructing the opponent’s line of vision or
- challenging an opponent for the ball or
- clearly attempting to play a ball which is close when this action impacts on an opponent or
- making an obvious action which clearly impacts on the ability of an opponent to play the ball
*The first point of contact of the 'play' or 'touch' of the ball should be used
or
- gaining an advantage by playing the ball or interfering with an opponent when it has:
- rebounded or been deflected off the goalpost, crossbar or an opponent
- been deliberately saved by any opponent
- A player in an offside position receiving the ball from an opponent who deliberately plays the ball (except from a deliberate save by any opponent) is not considered to have gained an advantage.
A ‘save’ is when a player stops, or attempts to stop, a ball which is going into or very close to the goal with any part of the body except the hands/arms (unless the goalkeeper within the penalty area).
