No, the claim is that there's a strict ordering of concepts when learning an assembly (or any language).
The conjecture is that using a simpler language makes it easier to teach the basic concepts, and that more advances features get in the way of teaching those basic concepts.
I'm not saying this is true, just that it's a reasonable hypothesis.
Learning a simple assembly may making learning a second assembly easier, but that's beside the point -- you need the basic concepts before any of the advanced/more complicated features become useful. And if the more advanced language gets in the way of learning the basic concepts, that could justify using a simpler language.
This is a hotly contested topic in CS education research, and we're not going to come to a consensus here.
