Yeah in retrospect I am surprised no one called out that Ogma’s VA voiced Orson. Maybe because no one really cares for Ogma unlike the entire fan base quickly noting that M Byleth, Mercie and Ashe’s VAs booked a NEW character lol.
I also think with the JP VA thing, it’s important to note that Orson didn’t have a voice before. So when they casted him, it was probably easy for them to just tell Ogma’s VA to do it because they were gonna book him for the summer alt in the studio that day anyway. Knock 2 birds out. With M Morgan, though, the VA has voiced him since the beginning. Regardless of what the future held, if IS wanted to do a M Morgan alt, they HAD to call his VA in, even if he didn’t provide his voice to Yashiro. There’s a commitment there to the voice that someone like Orson didn’t have, which made it possible to just double dip with VAs.
