No. There was a time way back when a back in motion had to be at least 5 yards behind his LOS, but now that applies only to a lineman becoming a back without setting. "1 yard behind the tight ends" means a backfield position, so if that player had already set, it's legal. And this "jump motion" is very common by teams using the double wing.

Fed was the last to abolish the "clearly backward" requirement for the MiM, and that was 20+ years ago.
