Yes, there are other purposes. Say, if you right-click an item in variables
tree and select, in the popup menu, the "Remember" command, the current
value of the item will be shown in a separate area for future reference.
But we need to show the full name of the item there. It's only for user, and
we need full name there.

Jim has explained this -- 'info-expression' is local name of an item
relative to the parent, while 'info-path-expression' is full name.
