i'd assume as someone already said lighting for 28L was off and they thought 28R was 28L and TWY C was 28R.
check this youtube video for reference:

and here is a youtube video with approach lights for both runways on:

on the other hand if you are sure that this is the runway and the tower says it's clear it's not far from disaster.
