Looking at FR24 am I correct in sighting that the traffic preceding the UAL was AF443 (also a 787 btw) and that traffic did land on 09R (cue ATC having 09R subconsciously in their head)? I also note (according to my FR24 playback) that the Easy apparently lined up at an intersection some 1000 metres from the threshold of 09R? That may explain why United didn't see it (or may have initially thought it was well on the roll at that point. There's still a lot of pertinent information missing.
