Section 18.25.4 says:
The server MUST NOT delete the directory entry if the reply from OPEN had the flag OPEN4_RESULT_PRESERVE_UNLINKED set.
It should say:
If the reply from OPEN had the flag OPEN4_RESULT_PRESERVE_UNLINKED set, The server MUST NOI delete the file contents until each directory entry is deleted and the file is no longer open.
The existing second and third bullets are directly contradictory.
