Stop-loss order terminology

I came across the term stop-loss order buy , in a text book but was not sure if this was referring to a stop-loss order or a stop-buy order?

I understand the basics of the stop-loss and a stop-buy orders. I think it’s just the terminology which is confusing me. Can anyone explain this?

Probably a stop-loss order on an existing buy/long position.

By the way the common term for stop-buy is actually buy-stop (you order to buy a security at a price above the current market price so your order isn’t executed immediately).
