Thanks for flagging these style issues.  I've proposed these changes in a
Github Pull Request [1], except for the comma changes (which appear to be a
contested point of English style).

Yes, this is a bit odd, as is the forward reference for "ech".  However, it
avoids disrupting the flow of Section 7 with extensive subsections, and
helps to highlight important material.
