The same orientation holds true if you were running it over a table saw, jointer, or planer for the reason Harry gave. In fact, cutting on the TS with the convex side down can be really dangerous as it can cause the blade to bind and toss the work piece.

This accident was an early experience with my first table saw. Hit me in the solar plexis and the bruise and pain lasted for months. :crying:

If it isn't flat, I don't put it on the table saw, not anymore.
