I'm arguing it's not, and I still don't agree with your understanding of
the operational model, again, take a look at what I wrote in my last email:

Also take another look at
specifically the table that shows another way of writing the ignore
rule. This again shows my understanding of rule 4 is correct.

Specially look at the following equivalence:
X Y × Z W ⇒ X (Extend | Format)* Y (Extend | Format)* × Z
(Extend | Format)* W
