Large Meeting Subscription tied to one or both pro accounts?

[ZeroWasteUSA]

We have two accounts that are tied to one billing email address. (Let's call them Zoom1 and Zoom 2.)
We also have a Large Meeting (1000 attendees) subscription.

I see that the Large Meeting is tied to Zoom1, but I'd like to temporarily tie it to Zoom2.

It looks like the answer here:

But I want to confirm. We won't just lose the license if I switch the large meeting sub to Zoom2 for a day, then switch it back to Zoom1 afterwards. It looks like I should be able to accomplish this from the login at Zoom1.

Are my assumptions correct? Thanks for your answers.
