I never heard or read that links pointing to dead end (dangling or node) pages carry less PageRank than other. If this is again a new pantent, then again I assume I have missed something.
These links do not carry less PageRank than other - they carry the same proportion of the PageRank to the page that is nofollowed, but after this the PageRank evaporates. It flows to the page that is nofollowed, but cannot flow out of it to circulate back to the rest of the site.
