Horses have been that way at least since the stat changes. 100% chance on vitality = 2 points in vitality every time they level. Since they start with 1 they end up with 41 base vitality at level 20.
Was handy during the period when horses had very low health in general. I’d always raise multiples until I got one with an 86% or better vitality chance since the 14% from vines would then make it 100%.
Too bad thralls don’t work that way.
