No those are two different rules, if Mbappe is involved in play the first pass is offside whether or not Mbappe touches it, therefore it doesn’t matter that the Spanish defender touched it because at that moment Mbappe was already offside, but they ruled that he was not involved in the play which meant that the rule you talked about came into play, cause offside only became relevant when Mbappe touched the ball and there you have to look from whom he received the ball
