The only thing it "might" be is possibly they might have had somebody in Mason's bracket at subs and didn't want to give him any sort of a "heads up" (seeing the who/how/etc) about who he might be facing. WHICH, is a completely separate discussion from this thread.
I can see that side of it a little bit, but control the room and the match ups and it should be able to be managed without giving up any big secrets.
