It's easy to miss, because the key to the letters is given in running
text a hundred lines away. (man chmod is a loathsome example of this
format.) The reference below is much better, as the figure is a table

The state is identical in both cases, hence using the same letter.
OTOH the paths to that state can be different, and that's significant
because installing and then purging a package can have side-effects
on the system that don't get reverted to the inital state, eg the
installation of Depends/Recommends.
