>>How is this different than the oHost property/object in SetObjRef.prg? It's storing a reference to the form on the object inside the form. But there isn't any special handling of the object at the form level.

It's used by all the classes in _base.vcx.
Home() + '\FFC\SetObjRef.prg'
All the _base.vcx classes have a SetObjRef() method that "DO (this.cSetObjRefProgram) WITH (this),(tcName),(tvClass),(tvClassLibrary)"

SetObjRef.prg
LPARAMETERS toObject,tcName,tvClass,tvClassLibrary
&& oHost is a reference to the form
IF PEMSTATUS(oObject,"oHost",5)
oObject.oHost=toObject.oHost
ELSE
oObject.ADDPROPERTY("oHost",toObject.oHost)
