I'm having a problem seeing when it would be necessary to look back up a 
tree. At first sight, it seems to me that this is only necessary when 
you're carrying out processing during tree construction. If you defer 
processing till after tree completion, then surely you can always pass 
the required information down, rather than up.

Or have I missed the point?
