That's true for very short knives, but most likely not an issue for 45-48 mm tall knives.
Knives can also feel taller or shorter depending on the handle size and shape, size of the neck (emoto) as discussed here. I've experienced this myself, with a pretty tall knife feeling much shorter.

Good point regarding the way the neck is shaped. I think we're just saying in general (all things equal), what is the difference between taller and shorter knives. I would be curious to try a really short blade to see if better food release due to less contact would actually happen the way I envision or if that would just cause food to topple all over everywhere.
