By "alternate timeline" and "doesn't connect to their own"...what do you mean?

I'm guessing you mean that they only go back to a point in which pulling their remnant to the present won't affect the timeline?

Because an "alternate timeline" implies a completely different timeline where things happened differently, like Thomas Wayne becoming Batman. They seem to be making a brief alternate timeline and then take themselves from it, creating a remnant.

I don't think that timeline remains afterwords due to speed force.

Doesn't need to be that alternate to be an alternate timeline.
