This read-create RowStatus is, per its source description, simply the status of this conceptual row in the connection table, used to create, activate, or destroy entries. Admins (or the discovery agent itself) use this to manage the lifecycle of a topology connection entry, and several sibling objects in the row (like ptopoConnRemoteChassisType/Chassis, RemotePortType/Port, and ptopoConnIsStatic) become immutable once this is set to active. For example, an NMS manually documenting a connection would set the identifying fields first, then set this object to active(1) to finalize and lock in that connection entry.
