Well the current text apparently **is** confusing. 
The issue has been raised in the IEEE, and as I try to interpret the
text for them, I understand why they find it confusing. 
Your spec says that a deleted row is considered a changed row, and
changed rows can be downloaded.

Let's walk through your proposed text backwards to see the syllogism.
Premise 1:
	"if the row ... is created or deleted"
	then the "row is considered changed"

Premise 2:
	if "rows changed since a particular time"
	then application allowed "to download ... those rows"

Therefore 
	if "row is deleted"
	application is allowed to download the row

This is incorrect; as you say above "Agents never download deleted
rows"
But your text says the opposite!
