I suppose that depends where you're getting your definition.  The
groff(7) man page and the Texinfo manual define \: as a "zero-width
break point," which does not suggest the observed behavior in the way
your alternate definition does.

groff(7) calls \& a "non-printable, zero-width glyph" but the Texinfo
manual calls it a "zero-width space."  However, \& does not have the
hyphenation-resetting property that \: does.
