This is not correct. .de simply overwrites a previous definition
without notice, similar to TeX.

In general, the user shouldn't define *any* macro within a man page --
many man2xxx converters understand only the limited set of man macros
(and probably a few raw troff commands). The next groff version will
contain an-ext.man, which defines a bunch of useful macros currently
missing in most man macro packages.
All man macros are uppercase. If Joe User really want to define
something, I strongly recommend to use mixed-case macro names, for
example <uppercase><lowercase> -- only the `Tm' string register is
defined in the man package (and its extension).

Yes. Defining macros before .TH is always problematic since .TH is
often defined to switch between `man' and `mdoc' (redefining .TH
afterwards).
