Have a few questions around JAL award holds on AA. New to AA so apologies if this is dumb. Tried reading all the threads and couldn't really find a direct answer

Found a flight with availability in J for 1 pax. I put it on hold for P1. An hour later the flight is still showing up as searchable / in inventory. My question(s) are as follows:

1. Can P2 also put this same itinerary on hold? If so, what happens? Do we both get ticketed if we both 'purchase / confirm the hold' at the same time?
2. If P2 buys this ticket outright with miles right now, what happens to P1's hold? Is it still honored?

In case it isn't clear, I found a preferred date of travel but only for 1 pax. Was planning on holding the single remaining ticket and continuously looking to then book P2 hoping avail opens up. But now it's still in inventory so I was wondering if I could potentially just book + ticket both pax now?
