An Abu Dhabi airline with an A380 landed on the same runway 11 days after the Air India incident, but that movement was planned. I think that's why the new runway had the full paint markings at the time. Having seen both runways it would be very easy to make the mistake given the new one is 60m wide with dark surface and with full paint markings (which have since been partly obscured) and the existing runway 45m wide, a lighter surface colour, faded paint markings and no lights. Runway lights on the existing runway are now on permanently to clearly identify the correct runway.
