Large Meeting Subscription tied to one or both pro accounts?

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.
