Makes sense to me as well Leto...
But by the same token in a way, Precognitive Dodge could be interpreted in many ways depending on the incoming attack... Especially in the case of Terminator Armour, maybe you move slightly so the shot automatically hits one of those thicker areas of the armor normally "under the effect of the field save", or perhaps you batter a bolt shell/solid projectile/grenade out of the air with your basically indestructible force weapon.
Or what if your psyker is under the effect of warptime? Still no "Dodges", but now the psykers senses and reactions are hypersensitive... and he can move very fast even in terminator armour.
Fluff vs Mechanics, age old battle.
