Romary in Kio Arc definitely looks older than Emily in Asemu arc, with Yunoa as the other extreme. And surprisingly, they kept HanaKana as Romary's voice.
Well, this 3-sided view between the 3 generations is definitely a unique thing in a Gundam series, though it's not an excuse for the scriptwriter to not get fired.
I bet this will go down the path of understanding between the 2 sides after a reconciliation between the 3 Asunos (at least before any of them dies if any will).
