Um, not exactly. I remember reading in the 8i docs and then just confirmed with our Oracle DBA that the 8i and higher versions of Oracle no longer work from the bottom-up. It's indifferent now due to optimizations in the query engine (I'm not all that big into the "under-the-hood" features, so I don't have more details than that). I would agree with Dave Watts's statement that using Oracle's EXPLAIN PLAN (which, yes, is the equivalent of SQL Server's SHOWPLAN) to prove this concept would be your best bet.
