Yes it does refer to figure 3. I agree it is slightly confusing.

By "Y, a node whose next hop is P"

we mean that S's next hop towards Y is P

and conversely that S's next hop towards Z is not P

We will try to clarify that in the next version

Interesting paper. I'll read it in depth later.

There are a number of furhter optimizations which can be applied to 
the not-via iSPF computation.

Have you thought about the effect of the use of the "early 
termination" once the not-via addresses have been re-attached.

Thanks for the first two

actually the use of "were" (the subjunctive) is better English than 
"was" in this context.
