There is also a fourth situation:

    (4) user has aspell installed, but uses ispell with ispell's dictionaries

AFAIK, the situation (2) doesn't exist.  There are the following
situations instead:

    (2) user has aspell installed and uses the compatibility script
        `ispell' as a wrapper around aspell with aspell's dictionaries

    (3) user has aspell installed and uses `aspell' executable with
        aspell's dictionaries

(2) is detected by checking the output of `ispell -v'.
(3) is configured by users by changing ispell-program-name to "aspell".

After the change in flyspell.el it doesn't work with the `ispell'
compatibility script.  Maybe ispell-really-aspell should have more
values to distinguish between (2) and (3).  (3) can be detected
by matching ispell-program-name against the regexp "aspell$".
