Turkish Airlines aircraft is not moving but it is definitely not at the final parking position. There must be something with the jetway or something else. Ground control should not give the Asiana taxi clearance before its way is fully clear.
In many airports, the gates are not ATC responsibility. The aircraft gets handed over to ground handlers and anything that happens thereafter (delay in getting on stand etc.) is between the flight crew and ground crew, none of ATC’s business. ATC cannot see if an aircraft tail or wingtip is hanging out a bit far from potentially a few km away up in a tower. This is the responsibility of the commanders of taxiing aircraft.
