update does roughly

undo
replay (or apply-delta)
redo

You'd probably get the same behavior with

$ tla undo && tla redo

undo means compute the changeset, and apply it in reverse to the local
tree. The changeset will say "this directory has been added". So, the
reversed changeset will say "this directory has to be deleted". In
this case, I believe tla does "rm -fr" on the directory.

That's a known issue (Aaron reported this a while ago), but it seems
that none of baz and tla fixed it.
