From what I understand, it's a warning about the quality of the 
implementation at the time the tutorial was written.  In the ideal, either
1. it's not possible
2. it's supported

From my observations, update does the equivalent of
tla undo $current
tla apply-delta $current $latest
tla redo

All of those should be safe.

It's doubtful that star-merge could behave badly for the case of tagging 
into the same branch.  Perhaps it could behave badly in other cases, by 
selecting the wrong reference version.

Replay doesn't follow ancestry, AFAIK.  It may stop at the most recent 
continuation.  I only replay revisions, not versions, so I wouldn't 
know.  Replay really should follow ancestry, but that means it needs to 
know what revision to start with, and what revision to stop at.
