The statement was specifically about Viera, so no, it didn't include Hrothgar.
It's pretty clear that they (and Miqo'te) are all differently constructed models and what works for one doesn't automatically work for another. The ears are controlled and applied in their own specific ways that may be attached to the hair or the head or an independent selectable piece.
Miqo'te can't choose their ear shape; it's tied to the hairstyle. Viera ears are independent of the hair. Hrothgar ears were permanently moulded into the head but that may not be the case for the altered version that will exist after tomorrow.
You can't assume how one will work based on the other.
