Cooper's Mistake.
In the Season 2 finale, Cooper is sat with the Man From Another Place, who tells him "When you see me again, it won't be me".
After coffee with with some friends and a strobe light, Cooper then goes off to another room which is empty except for the furniture. He goes back to the first room where the Man From Another Place tells him "Wrong way".
If the first instance of Man From Another Place is to be believed, then he shouldn't have then gone back to the other room because the Man From Another Place who told him "Wrong way" was not the same one.
