This is an absolutely valid and substantial observation in my opinion as well. The structuring of mathematical expressions -- that is, the choice of symbols or notation, and the organizing and grouping and ordering of terms within an expression -- is a vitally important feature in reading, grasping, recognizing, understanding, and internalizing what they are saying, and what are their connections to other expressions and concepts. There is no set of rules for doing this -- only a large body of informally accepted conventions that have evolved over time, but that are very widely used. (Anyone who wrote a treatise on e-m theory and used E for the magnetic field and H for the E field would be a fool; even writing the Poynting vector as H cross E with the normal meanings of those symbols would be unnecessarily stupid.) I appreciate why Mathematica does -- even has to do -- what it does in structuring mathematical expressions in its internal operations. But it's very hard work to convert between that and readable mathematical expressions.
