Thanks for an explanation.

I would say that "prior" is not THAT different from usual "parent",
rather than it is not ANY different.

My doubts about recording previous head of a "union" (pu-like) branch 
is that for merge (e.g. 'pu' to 'next', cherrypick to/from 'pu', 'pu'
rebase) is that for merge algorithm all parents are equivalent, with
eventual exception of first which can be treated special ('ours').
