all adds / removes are actually lumps added to original request - all 
lumps added in a branch route are removed after  its execution, so all 
changes (add or remove) will be cancelled for the rest of the branches.

so, if toy remove a hdr from a branch route, the hdr will still be 
visible for the rest of the branches.
