the TPS has three wires as it's basically a rheostat. seems likley he measured across the wrong wires to have the resistance go in the wrong direction. That doesn't mean the TPS isn't bad tho - I can't say as to that. If my memeory hasn't totally failed there should be an old post by Beav in which he describes the need for something like a storage O-scope to check the TPS. Search is your friend in this case.
