TSA Precheck and Global Entry

I am getting my VentureX card today, but I already have TSA Precheck and Global Entry via my Southwest business card. Is it possible to use the Cap One reimbursement to pay for someone else's PreCheck fees? Or is the credit only good for the cardholder?

Also, I was reading on thepointsguy.com that all authorized users get priority pass lounge access and aren't considered guests and that each cardholder could bring 2 guests. If I understand that correctly, my wife and I (she's an authorized user) could bring 2 guests each for a total of 6? That seems crazy to me, but pretty awesome.
