This "recommendation" is only really relevant if you have hydrogens with bad
atom names. In some cases, it may be simpler to strip and regenerate them
than to figure out where the bad (non-IUPAC) names came from.

Amber won't strip hydrogens unless you explicitly ask it to do so, e.g. by
setting the --nohyd flag in pdb4amber (which is not the default).
(Running reduce will also change hydrogens, but again, you have to ask it to
do that.)

You should be fine: a "carefully prepared" protein structure ought to have
no problems with hydrogen names.
