Swords are named by western order, so Kiyomitsu would be like a surname. A lot of the swords are referred to by their given name. Some are just because some have the same surname (Like Toushirou or Kunihiro). Although, some just prefer/are used to being called by their surname.

With Kiyomitsu and Yasusada, I gues it's more of a "friendly and informal, but not a first name basis" kind of thing. Additionally, some swords' last names are used as part of a nickname (but you know who is talked about), like Sada-chan, Kane-san, Micchan, etc.
