Section 4.1.6 says:

It is important to note that if Ru and Rd are adjacent LSRs in an LSP
   for X1 and X2, forwarding will still be done correctly if Ru assigns
   distinct labels to X1 and X2 while Rd assigns just one label to the
   both of them.  This just means that R1 will map different incoming
   labels to the same outgoing label, an ordinary occurrence.

It should say:

Notes:

R1 should be replaced by Rd since there is no reference for R1.
