For the first question, perlop goes on to say:

If the final value specified is not in the sequence that the magical increment would produce, the sequence goes until the next value would be longer than the final value specified.

I read that to mean, 'e' .. 'd' runs through 'z' and stops at 'za' 'aa' (thanks ikegami).

Update: Correction!
