strip: clarify comment around bundle create

We may create two bundles, one for the changeset actually stripped, and one
for the changeset affected by the strip we want to keep. (Changesets with a
higher rev number than the striped ones).

For soft stripping, we still need to the first one (used for "restoring" the
changesets), but not the second one.

We start with clarifying which bits of the code is used for what.
