Spot on, GIII and P88. If fuel is managed competently, there should be no need to change fuel tank selection after TOPD (subject of course to some unexpected delay or other surprise).
(Interestingly, a few flight reviews ago - in a Bonanza - the ATO told me the story of a practise forced landing that turned into a real forced landing during a recent flight review in a Bonanza. The pilot under review must have been doing quite of bit flying in Cessnas, because during the PFL he inadvertently set the fuel selector to point to position between "L" and "R", which position is not "BOTH" in a Bonanza! The engine duly stopped producing power and they landed in the paddock. The fuel selector was found in the wrong position, restored to a correct position and the aircraft flown out of the paddock.)
