Second yellow for wasting time with substitution

Polish referee people Pawel Gil did something in Europa League last Thursday I’ve never seen before. He gave a second yellow for wasting time to a player who was wasting time during his substitution.

The situation: In the match between Malmö and Austria Wien the away team leads with 1-2. Grünwald from the Austrians has scored one of the goals, but also got booked in second half. He was about being replaced, substitute was ready. Grünwald applauded to the fans one more time, just before Gil runs to the sidelines and gives him his second yellow card. The substitute already ran into the field, but he had to go back to the bench.

It’s pretty difficult to find a website where the situation is shown, but I finally found it here (last 12 seconds).
