It would, which you would not want to do normally but
which would be correct if you were displaying stems in
tab before calling \hideNotes.  This is not so much a
problem with \hideNotes as with the way \tabFullNotation
is implemented.  You would have exactly the same problem
with \hideTabNotes (or whatever it might be called).

This is a limitation of using predefined commands - when
several changes interact there is no means of testing
anything.  The fix would be to use context properties
rather than \hideNotes and \tabFullNotation.  These
could then be tested in the engravers, and the engravers
could work out what values the properties should have.
