When a output transformer is designed and wound, there are certain unavoidable capacitances between the windings. Depending on where these capacitances are located within the windings (close to a AC ground point vs. clear at the other end of the winding, etc.) that capacitance will short the high frequencies to ground. If a transformer designed for one end to be close to AC ground (the B+ connection) and the other end connected to the plate of the output tube is wired backwards, the winding capacitance that would not do harm (because of how it's placed) to the FR of the transformer is now placed where it does the most harm to the FR.
