SSO Team's Excuse for the Hanoverian Gait Issues

Jess Northwood apparently works with the company or something and this is what she said that the team had to say about why the legs were so messed up and made the horse look lame.

"There's a limitation animation cycles, like, you can't really stretch out the legs anymore without having them be super rushed. So that's why we have this like kink in the hocks and it doesn't really fully straighten out."

My question is, how was this not an issue with the friesians? There's so many breeds in the game that don't have this problem. Like the arabians, jorvik wilds, and several others... What do you guys think about this excuse?
