I don't think so, well, not that i understand how magical sword girls work in the first place, but maybe it depends on the sword? Like, the holy sword is completely flat, maybe that's related to its human form, the cursed dagger is curved and short, and the ice sword is long and irregular? Perhaps a newly created imperial is unable to communicate properly and/or transform. This are just my assumptions based on nothing XD.
But i wouldn't worry, i'm sure Tatarra will continue to give "maintenance" to any and all swords that he encounters.
