You've now asked this question multiple times, and have gotten at
least one response.  Why are you asking the same question again?  What
did you not understand about the previous reply?

I'll note that you continue to quote the text in a way that makes it
seem that the sentence "Some examples may make this clearer." is
specific to the text about the expansion of the PARAM arguments, when
it is actually its own paragraph, separating the general description
of the semantics of $(call) from the (general) examples of using
$(call).

There are no examples to illustrate that passage.  If you think that
every statement in the manual must have an example to illustrate it,
then I think you expectation are too high.

The example you cited from the manual has nothing to do with that text
about special expansion rules.

The former, the values of parameters.  This was illustrated by the
reply to you post back in August.
