Movie Render Versioning, am I doing it wrong?

Using Movie Render Queue to version renders, and it seems that it will increment the version with different shots. If there is a Shot_A_v1 and I render a Shot_B then it gets the version of v2, resulting in Shot_B_v2.

Is this the way it works for everyone else or did I add my {format_string} incorrectly?
Is there a way to keep versions consistent between shots, or do I need to send them to a different folder?
