The marking "TOP" on the rings is to tell you that it is the top of the ring that faces up.

And ditto Tools on the other. The reason for the beveled edge on the bottom ring is to act as an oil scraper. The bevel allows it to ''ride past'' the oil on the up stroke but scrape,or squeegee, the oil on the way back down.
