If you are referring to the aircraft for CX870, then no. That aircraft will only sit in SFO for only 2 hours and then do the turn around back to HKG as CX879 around lunch time. The a/c that will sit extensively for the night CX873 is the one that arrives as CX872 which CX has done routinely for quite a long time already.

Interestingly if CX879 is delayed for departure (either caused by domino effect of the late incoming CX870 or for any other reasons) and CX872 arrives early from the scheduled time, we can be seeing 2 CX 744s parked at the SFO int'l terminal at the same time. Don't know if SFO has enough gates or can handle two CX 744s at the same time during that particular time frame.
