It may have something to do with brake heating. Today in Jeddah Emirates A380 requested nearest to their parking RW34L while everybody else were using 34R, and gave brake heating during prolonged taxi as a reason.
On the other day they were holding all traffic on the main taxiway for about 20 min as they could't taxi due to hot brakes. That was on departure by the way...
