In the grand scheme of things it doesn't really matter because they were going to land on Taxiway C if it wasn't for the actions of UAL 1's and PAL 115...
it notes they moved throttles forward at taxiway W. not beginning the climb for 2.5 seconds (until after PAL...)
Yes, certainly seems UAL 1 woke them up. In the image, not only does PAL have landing lights on, so does the next ac inline.
That is a very frightening read.
