It sounds like they are looking to remain flexible as they are using the new facility for F2/F3. I can imagine if they find entry into F1 then either that is an existing team with existing facilities or if they get a new entry they maybe move F1 into this facility and F2/F3 share or are moved elsewhere.
As to them buying Renault/Alpine team, I swear I saw a rumor somewhere just yesterday that was speculating they were in the hunt for RB (Marko saying multiple groups interested in buying RB). Lots of rumors, who knows which are true.
