Let me put it this way, Without Pyrrha, the weapon cannot function, I believe she uses her semblance to make it work and change form, like when it goes from the Gun to the Javlin form, she uses her semblance to bulid the blade head, it also makes sense for how it can transform in mid-air, when she lets go of it. we have seen her use her semblance on it a number of times, this also opens the possibility that she can construct more forms out of it on the fly, like splitting it in half and having two swords. She has spent so much time with it, it is totally under her control.

If someone else in their World picked it up, they could only use it on the form it is stuck on if that, and if she was near by, it would resist their control of it.
