Initial size of the window should be taken "when calculating reference
point"
It says nothing about the size of frame decorations.

The purpose of that statement is to clarify question:

"Do I first  decorate the window and then calculate ref. point ?"

crearly answer is negative.

Well, ICCCM description of all that is garbadge and over years generated
nothing but confusion.
While reading the entire paragraph you'll find out exactly what
"reference point" specs are talking about, how it should be calculated
and how it should be applied. Clear formulas. No confusion of frame/client
ref points. Just copy and paste it in your code - and you are done.
