[linux-lvm] snapshot looses origin when other snapshot is merged to the same origin

I have a question related to multiple snapshots of the same thin volume. 
My scenario is that I create a thin pool, a thin volume and two 
snapshots of that thin volume. Both snapshots have the thin volume set 
as the origin volume. However, after I merge one of the snapshots to the 
origin then the second snapshot looses information about the origin.

The question is if that is an expected behavior or if I am doing 
something wrong? Is there a way to make the second snapshot keep having 
the origin with merged first snapshot as its origin?
