That is not even possible, you have to cut a master to press a record. All vinyl has separate master. Mastered well is a different topic.
English language has quite sometimes expressions that do not positively identify what is meant.
Take word "design" for example. It can be design in technical sense ( it is a design based on satisfying this and this...) - but also can be design as form or fashion ( beautiful Italian designed shoes/fashion/car/whatever ) - and although not mutually exclusive, they DO NOT NECESSARY MEAN THE SAME THING.
Same with word "master". You have misunderstood what master for LP release is. In this case, it is NOT meant the vinyl "mold" - as explained here :

What was meant was master from which the actual disc is then cut. This master not only can be different from the one intended for the CD (or cassette) - IT HAS TO BE DIFFERENT. Vinyl mastering has quite a few limitations - which, if not observed to the letter, can lead to useless cut as the most benign thing - to the destruction of the cutting equipment, most notably the cutter head. There are VERY precise prescriptions how the master from which a physical master disc will be cut has to be prepared. In short, bass below certain frequencies has to be monoed - or the excursion of the cutterhead in vertical direction will exceed the thickness of the lacquer of the master disc, rendering the master disc unusable - and likely destroying the cutting stylus ( expen$$ive) . Further limiting of the bass has to be done because of playing time compromise. That is why, usually limited edition, 45 RPM releases of certain hits as singles on 12" LP sized disc will sonically clobber its regular same size disc containing the whole album - the limits and limitations have been reduced to an absolute minimum, sacryfing playing time instead. There are also limitations for the treble - which can be circumvented by the use of half speed mastering ( which is again an art all of its own and is, unfortunately, NOT a
deux ex machina ).
Furthermore, "master" can differ from another "master" in whether or not any compression has been used, the degree of that compression, equalization, NOT even going into "mastering", which is to say mixing the song from the master tapes or files in a different manner ( say singer put a bit to the fore and slightly to the left, bass somewhat moderated, sax a bit darker and more to the right than in previous "mastering" - etc, etc, etc ).
"Master" simply has too many meanings in English for everybody to EXACTLY understand what is actually meant.
