Yes, I think adding that would improve readability.

Hi Joel,
Sorry for the late reply, I missed this email.
Thanks for the second round review. You are right, the stack will grows
downward, but only with the relay nodes, not all nodes along the LSP.
The mechanism is described in section 4.2 paragraph 4.
Do you agree if I add the following:
This stack grows downward, with relay node addresses further along the
LSP appearing lower down in the stack. Please refer to section 4.2 for
the relay node discovery mechanism.

Regards
Lizhong

    Document: draft-ietf-mpls-lsp-ping-relay-reply-10
          Relayed Echo Reply mechanism for LSP Ping

    Summary: This document is ready for publication as a Proposed Standard

    Major issues: none

    Minor issues:
          In this document, the address stack grows downward.  While
    reasonable, I think that in the absence of warning of this, readers are
    likely to be confused when they read the detailed procedures.  I think
    the document would be helped by adding the sentence:
          "This stack grows downward, with addresses further along the LSP
    appearing lower down in the stack."
         This could appear right after:
          "-  Stack of Relayed Addresses: a list of relay node addresses."
    in section 3.2.
