So this seemed so very cool that I wanted to learn more. There were a few problems, however. The direction of Nishimura is traveling opposite to what this video shows. I eventually found this video is from Comet Encke back in 2007 as observed by STEREO-A. https://en.wikipedia.org/wiki/File:Encke_tail_rip_off.ogv

Well I can't be that mad even though I was tricked because this is a really cool video and I learned some new things. Nishimura did go through a tail disconnection event. But buyer beware, eh?

I didn't even think this was a thing. Neat post.

So where's all that water gonna end up? Also does losing what appears to be a not inconsiderable amount of it's mass, has the orbit changed?
