Technically, Sengo Muramasa is referred to all the swords made by the first Muramasa. It is assumed that Sengo is like Doudanuki and is an amalgamation of Muramasa swords crafted by the first Muramasa. Myouhou is just the only known remaining named sword smithed by the first Muramasa.

Take note that the first edition of the official illustration book did specifically mention Myouhou Muramasa in Tonbokiri's description, although it was removed in later editions. So there might be a chance the actual Myouhou Muramasa might show up later, or it could have been a misprint and was referring to Sengo all along.
