You cannot compare these two matches.
The first searches node1 and all node2 in the subtree.
The second one searches node2 and lookup the parents.
Of course the second one is faster, but how do you
position on parent of node2?


Maybe you want compare 
  match="//node1//node2" 
with 
  match="//node2[ancestor::node1]"?

Then both will be inefficient (complete tree search).
