Reuse 40% back in pts when you redeem 50k+ offer?

Has anyone tried to use the 40% back in points when you redeem at least 50k pts offer more than once? I got it this week, used it today, and it hasn't disappeared. Since the points don't get awarded for 2 weeks, there's no easy way to tell if it will work twice, so I wondered if anyone's tried it.

FWIW, within the app, it doesn't state that it's a limit of 1 use... but from the website, it does. (Similarly, from the app, it states that the offer can't be combined with any other promotion, but from the website, there's no such caveat.)

Any thoughts?

In the app it also says "Limit 1"....at least on my app it does.

): Won't chance it, then. Ty!
