Do these two types of mouli graters do the same thing?

I would like to know whether these two types of mouli graters found in the internet do the same thing, work the same way, or are actually used for different types of food.

How do they differ in terms of what they can prepare and how they work mechanically?

The biggest noticeable difference is that one is "round" and the other is "square", but if someone could post a video of how the latter is operateed that would be great. I cannot imagine it.
