The guy would have been penalized simply for timing his hit well, being the same height as the receiver and wearing a face mask. 9 times out of 10 that turns into a perfect tackle with no debate about targeting. Because their helmets touched first and the height matching perfectly it's suddenly an issue. Glad the refs on the field recognized it for what it was. A complete incidental event with ultimately good form. That's not the type of play the targeting rule was designed to eliminate.
