"1 drop of pyrogen-free Water has been added to render vial sterile upon autoclaving"

I bought some 30ml sterile vials at a local pharmacy. They say on the side:
"1 drop of pyrogen-free Water has been added to render vial sterile upon autoclaving"

so, I assume that they're not sterile as-is.

Must they be autoclaved or would it suffice to put them in the oven, vented with a pin, at 275f for an hour?
