He's confusing concepts. The exception that allows a player to catch a throw-in pass doesn't apply to anyone but the first player to touch the ball, but that doesn't apply to any other situation on the throw-in.

He's also getting that concept incorrect, but that's a different thread for your next conversation with him. I'd question whether he's "knowledgeable" about the rules. He may well be a great official, but his rules knowledge is suspect.
