I strongly disagree. The pilot is inside the neck, the flash hole has nothing to do with how the cutter cuts. As long as the pilot is the same size, or slightly smaller than the inside of the neck, it will cut square. AND if the pilot threaded portion isn't bent where it screws into the cutter.

If you are relying on a thin, flimsy, brass case neck, with maybe a third of an inch of bearing length, riding on the trimmer pilot to square up the trimmer, you will be disappointed.
If you don't believe me, drill out the flash hole to the diameter of the primer pocket, then trim the cartridge and see what you get.
Assuming you make more than just one full turn on the cutter, it really does not matter whether the cutter is square to the pilot, since whichever cutter blade is lowest will cut the entire mouth the same all the way around (that one blade may get dull more quickly, but that's about it). What matters is whether the axis that the cutter spins on is true to the axis of the case, and that is controlled by the pilot at the neck end and the pin in the flash hole at the other end.
