I don't really know what you mean here.

It's trivial to confirm that this is not the case.

% cat ./foo
#!/bin/zsh

foo=2
typeset -p foo
% chmod +x ./foo
% foo=1
% typeset -p foo
typeset foo=1
% ./foo
typeset foo=2
% typeset -p foo
typeset foo=1
% . ./foo
typeset foo=2
% typeset -p foo
typeset foo=2
