The first test ("dependent"), fails due to combination of two factors:

1. You have "../core" in client/Jamfile, so "../core" will build "stdafx" too,
   and so "client" will get usage requirements of that target no matter what,
   including <pch-header>

2. Your patch does not include "kill pch-headers" change to

If I modify the end of the rule to be:

        local raw = [ $(subvariant).sources-usage-requirements ] ;
        raw = [ $(raw).raw ] ;
        raw = [ property.change $(raw) : <pch-header> ] ;
        ECHO "XXXXXX" $(raw) ;
        result = [ $(result).add [ property-set.create $(raw) ] ] ;

and then replace ../core with ../core//core, I get a single -Yu option when
compiling client/main.cpp. (I got double -Yu option before).
Instead of replacing ../core, you can add "explicit stdafx2" to core/Jamfile.

Looks like change to basic-target.compute-usage-requirements is the only thing
missing in your patch!
