In that case it doesn't: There were two Colombians offside on the initial free kick by James Rodriguez and because at least one of those two got involved at the action at the 6yard box (he doesn't necessarily need to touch the ball, it's already sufficient to get involved by blocking/impeding someone, blocking his view or just alter his play for the ball, f.e. standing in front of the goalkeeper almost always should be considered offside even if someone would stay away from the ball because the goalie would have to account for the player to deflect the ball and/or his view might be limited), the game was rightfully stopped there. Therefore it doesn't matter who actually touches the ball afterwards and/or of whom it bounces off because he is consider an "active" player in the initial action for the ball.
Rule actually was changed last summer by FIFA and every major league. After further clarification/explanation there isn't actually any ground left to cry foul even though some Colombians don't get that:
"In addition to the already established principles that a forward – should he find himself in an offside position - is offside if a ball rebounds to him off the woodwork or from a rebound to him off an opponent, the new wording also makes clear that a deliberate save or deflection rebounding to an opponent in an offside position means that the linesman must raise his flag."
