That would depend on the backend, in ours we (well, the optimiser)
deliberatly rearranges statements to get fewest traversals, eg. refineing
on little-used members first to reduce the working set.

If you enforced the ordering of the path it would generally be slower, but
obviously that wont apply to all systems.
