That depends on your provider.  If they remove the old PTR records when
they add the custom ones that you request, then they'll only get the ones
you supply.  If they leave the old PTR records when they add yours, they'll
both be returned by the query.

Most software that does reverse lookups only uses the first name in the
response.  As long as that name resolves back to the original address,
things should be fine.  Since both your custom name and the ISP's default
name should translate to your address, you should be OK.
