Nah, no way of knowing without actually measuring, but I'd be surprised if that is more than 200 sq cms. Think about it, a large top measures approx 100cms from the back of the neck to the base, so the front on an angle like that will be around the same, & that logo is probably a bit less than 20cms wide (using the same logic of 100cms being the length of the full shirt) so I reckon they'll have measured it to be spot on the max allowed an extra large shirt.
