Your last part is not correct. Both jetties on 544, 545 and 546 are able to be used on 2 Airbus both left and right. No need to coach any of them. The timing of the flights is usually spaced apart. Its only 547 where the second jetty cannot reach 547R so that is a coaching stand. 548R is also coaching as there is only 1 jet bridge on 548 and when 2x Airbus park it goes on the left side.
