You are correct, but some of the moves mentioned (Flamethrower, Water Pulse) are moves that Raticate cannot learn via TMs, and there are ones for both those moves (in Gen IV, they're TM35 for Flamethrower and TM03 for Water Pulse), but Raticate uses neither of them, and the moves aren't able to be bred onto its base form, Rattata. Dig is a learnable move for it via TM28, though. Ice Beam is also learnable by using TM13 on a Raticate. So arguably, the Sandshrew and Pelipper splices were unnecessary.
