I mentioned it because PP and FF already had, I was just supplying the link. But what I said also holds true for the curtain and the missing player: you might be missing the forest for the trees, but if your job is to count trees it won't matter.
But suppose if instead of counting passes you were just told "watch closely and write down everything that happens": then you might well see them all. In those terms, it's the instruction itself that's misleading: you're told to look for one thing and are then told you missed something else.
