That depends on what you understood ;-)  It could be that you
understood it immediately, but incorrectly or inaccurately.

The above is inaccurate as well: text-derived modes for markup text
can also benefit.  Basically, anything where you have keywords that
are not necessarily words in a human language.

IMO, we should start with what the manual says:

     Flyspell Prog mode works just like ordinary Flyspell mode, except
  that it only checks words in comments and string constants.  This
  feature is useful for editing programs.

Which might try to explain the name, but in doing so, it misses the
opportunity to let the readers discover what that mode truly is and
what it can do.
