It's part of the "specification" that pid is used to identify a client
process. In this case the server is the client (strange as that may
sound), using the definition of client as the one that initiates the
communication (of the oplock break in this case).

The process ID is a "process" on the server and can be anything, it is
decided by the smb server and is not related to any pid you have sent it.

Which pid did you expect to see?

The FID tells which file is losing it's oplock.
