Walsh has rarely visited Hong Kong, let alone seen the vast collection post covid of Shark Tick tails clustering the aprons at all hours of the day. The frequency of movement to pre covid levels pretty much reflects the replacement of high volume wide bodies with single isle types. It appears the 321's for CX are the more frequent types now using Manila and not 777 and 330 and its my guess thats the CX management's way of allying the stats of volume with frequency.
