First question is whether you're in Cost Based or Rule Based optimization.
In RBO you are correct that it will read tables right to left unless
instructed otherwise by a hint.
In CBO, Oracle will choose what it thinks is 'best', which most of the time,
but not all of the time :), will be true.

This can get into a lengthy discussion, but I'll try to keep it short. In
general you can use this in both CBO and RBO, since in my experience doing
