I was first thinking that Message ID and Exchange Type are not very
important here either, but as I noticed that the same section do
explain Message ID earlier, and talks about Exchanges even when it
does not yet specify how different exchanges are indicated, so I think
this addition might clarify things.

Changed:

<t>HDR contains the Security Parameter Indexes (SPIs), version
numbers, and flags of various sorts.  The SAi1 payload states the
cryptographic algorithms the initiator supports for the IKE SA.  The
KE payload sends the initiator's Diffie-Hellman value.  Ni is the
initiator's nonce.</t>

to:
