I have a rpm.spec with 2 Sources, one for the source code named Source0 and the second for the documentation named Source1 -- see below snippet of the spec --. The execution of the %doc directive jumps into the Source0 directory -- rendered in bold in the log below -- while it should jumps into the Source1 directory poco-1.7.0-all-doc in  as specified by the second %setup

So how could I fix this directory change?

Source0:           file://localhost/home/fandre/poco/releases/%{name}-%{version}-all.tar.gz
Source1:           file://localhost/home/fandre/poco/releases/%{name}-%{version}-all-doc.tar.gz
#%setup -qn %{name}-%{gittag0}
%setup -T -b 0 -qn %{name}-%{version}-all
%setup -T -b 1 -qn %{name}-%{version}-all-doc
%files doc
%defattr(-, root, root, -)
%doc %{name}-%{version}-all-doc/*
