They didn't say they were not lined up with the taxiway, they said they "believed they were lined up with 28R". Well duh! Obviously they thought they were lined up with the runway, they're not going to line up with a taxiway on purpose just for ****s and giggles. This is not the same as denying they were lined up on the taxiway as Underfire keeps banging on about. They also don't recall seeing aircraft. Again that doesn't mean they didn't see the aircraft, it just means they didn't recognise what they were looking at as aircraft, instead it "just didn't look right".
Nowhere does it say that the crew deny the fact they were lined up with the taxiway or that they overflew aircraft, they are talking about what they perceived at the time.
