I'll take a stab at this question too:
--
First:
I think that viewing reification as a process is unhelpful. I think it's
more helpful to view it as a relationship, as in:
X reifies Y
--
Second:
As far as I can tell, statements are used in two distinct ways:
(a) They are quoted
(b) They are asserted
From your example, { S'', S''', S'''', S''''' } correspond to (a), a
quotation, and S' corresponds to (b), an assertion.
[[[There may be more, such as: a statement may be asserted to be
false. But RDF doesn't support this directly. Rather, additional
constructions based on quoted statements are used (see
http://www.w3.org/DesignIssues/toolbox/).]]]
