The fact that the hole is on the bottom pin is not important. What is
important is that the hole at the change-key height does not need to
be at the same angular position as the hole at the master-key height.
It's hard to draw ascii art to show what I mean, but because the twist
holes are at a particular height when the key is inserted, you can
certainly see how at different heights the holes can be in different
locations.
