Flippa.com Pay with Different Paypal Account?

[LowPage TeaJit]

Is it possible to win a auction on Flippa.com and pay the seller with a Paypal Account having different Name than the name on Flippa.com ?

Or Flippa.com system has built-in button which connects to Paypal API, then the buyer makes payment on Paypal website and redirected back to Flippa.com and payment received into seller's Paypal account is confirmed?

Or is there some other way the process of making payment to website seller with Paypal on Flippa.com?
