I mean sure, they can use it wrong. If you REALLY want buy it now + auction, you use a reserve price. Say, start at a penny, reserve price of $50, buy it now price of $70. Then buy it now dies not "disappear" with 1 bid for a penny. It sticks around until you hit $50. If you really but no reserve and buy it now on an auction, you are literally flushing money down the crapper. Unsure why eBay allows this, maybe easy money for them. But this use case is user error mode, and not how anyone who uses eBay would actually sell on eBay.
