You could be right but for me it looks like he is confused (or at least changes his mind, he also took the red out with yellow). He momentarily shows the yellow to the keeper then bring it down, jesters no and then points to the striker.
Contact does not necessarily rule out simulation. For me although the keeper contributes to the very small amount of contact, it is instigated by the striker. He took a short step and moved his foot downward towards the keepers foot to make sure of it. What I can see as the point of contact is the striker's studs on top of the keeper's shin/calf.
