Yeah this point about different angles is very much how I understand Marx's thought and presentation. Bertell Olmen's book Dance of the Dialectic has some a good description:

The third mode in which Marx's abstractions occur is that of vantage point. ... There are many similar, apparently contradictory positions taken in Marx's writings. They are the result of different abstractions, but not of extension or level of generality. They are due to different abstractions of vantage point. The same relation is being viewed from different sides, or the same process from its different moments.

In the same mental act that Marx's units of thought obtain an extension and a level of generality, they acquire a vantage point or place from which to view the elements of any particular Relation and, given its then extension, from which to reconstruct the larger system to which this Relation belongs. A vantage point sets up a perspective that colors everything which falls into it, establishing order, hierarchy, and priorities, distributing values, meanings, and degrees of relevance, and asserting a distinctive coherence between the parts. Within a given perspective, some processes and connections will appear large, some obvious, some important; others will appear small, insignificant, and irrelevant; and some will even be invisible.
