Indeed. It isn't the mark that is significant, it is the fact that it disappears. This also seems to occur with various status effects that put a visual on him (Twitch's poison stacks for instance). I'd imagine that'll be changed in the future, but in the mean time, it remains a fairly easy way to tell if he has used decoy or not. While it doesn't help in finding the real one, it does stop you using abilities on a fake.
