So you are saying they are mutually exclusive: HELLO message by 9.4, all
other packets by 9.3. Can you make the text clearer about this. As
written it still could be interpreted as applying 9.3 to all packets,
including HELLO, and then applying 9.4 to HELLO packets. (Even though
this is nonsense if you think about it.)

No, it is NOT exclusive...

there is no Hello packet... there are just RFC5444 packets which might contain one (or in theory multiple) NHDP HELLO messages.

Its the same with IP and UDP... every UDP header is contained in an IP header. We are talking about two different levels of hierarchy.

DAT is processing both the RFC5444 packet header (which contains the packet sequence number) of ALL RFC5444 packets and the message content of the HELLO messages.
