I don't see the point of not doing that.

To me, a documentation bug is a bug in the documentation, i.e., the
program's behavior is the intended one, but the documentation doesn't
describes that behavior.  And that is what happens here.

Definitions aside, the fact is that currently, any user of the
MS-Windows port of Emacs will be confused when she reads about the
`make-pointer-invisible' variable and notice that the actual behavior
of the program does not match the documentation.
