They play for 200$, because 100$ does not hurt enough.

They play in Q4 because Sanchez would not ever play something else.

If Sanchez wins, Faye has the right for a rematch in QL. Sanchez can chose to not play the rematch in QL but then Faye does not need to pay him the 200$. Or he can take him on in QL, either winning another 200$ or losing his already won 200$.

Cmooon let it happen. Less talk, more action.
