There are two ways to see it though:

Either they know of the conversation between the VAR and the ref (which I highly doubt it) and they think it was not clear and obvious because the ref had seen it.

Or they don't know what was said and they are talking bullshit. Because if there is a red card, away from the play and it is not given, it is clear and obvious.

The rules are very clear, away from the play, hitting a player in the head is a red, there is not much room to maneuver here.
