AFAIK the above is not true and Harbour works exactly like Clipper here.
If not then please send self small contain example and I'll fix it but
I rather do not believe it's possible. This code shows that Harbour works
in the same way as Clipper:
memvar p
proc main()
p1("a"); p2()
proc test(); ?? "", p
proc p1; parameters p; ? p; test(); pp1()
proc pp1; private p:="A"; ? p; test()
proc p2; private p:="b"; ? p; test(); pp2("B")
proc pp2; parameters p; ? p; test()
I think that when you try to reduce the problem to self contain
as small es possible example then you will find the exact reason.

Not in situation as you described what above example shows.

AFAIK it is fully compatible here (except some Clipper bugs which were not
replicated intentionally)
