top mount sinks

I arrived at the house yesterday, took one look at the (quote) American Standard “self rimming” sink sitting on the countertop and said “that’s not an undermount.” The owner replied “the display at Home Depot said it could be undermounted.” Thinking he was mistaken and it had said something along the lines of “undermount model available”, I swung by the store and sure enough, affixed on what to me looks like a typical drop-in type self rimming sink is a sticker stating “this sink can be undermounted with an optional kit.”
