Just read it more carefully.

1. "Possibilities include"
                  ^^^^^^^

   It doesn't say that those are the only possibilities.

2. It points you to "`thingatpt.el' for documentation on
   how to define a valid THING."  IOW, for documentation
   what makes a THING defined for use by `thing-at-point'.

See above.  The word "include" doesn't mean the
same thing as "include only" or "comprise".  The
list of THINGS mentioned isn't exhaustive.

The English language includes the words "thing"
and "point" (but it also includes a lot more words).
