Please analyse this grammar for me. 'The man is at the back of the door'

The man is at the back door. The back door is the one at the back of a house.

I don't know whether there would be a possible meaning in Am. English for "in back of the door" (??) [=Br. English 'behind the door'].

These are two possible typo-based explanations; otherwise, I can't think what 'at the back of the door' could mean - except in the extremely unlikely context of a very thick door made up of layers, used to flatten a man!
