It's an old way of requesting that a threading database be initialized.
It's obsolete now given the near-universal implementation of XOVER.  I
doubt there still exists any server that supports XTHREAD DBINIT and
doesn't support XOVER, so the code that sends that command could probably
just be removed from trn.

I believe that some servers used that form instead of MODE READER at some
point.  It's also obsolete; everyone who needs it uses MODE READER.
