Dear Yan, Yes to your first question. The STATUS determine the connectivity or otherwise of a branch.
On the second question, there are algorithm for running Distribution power flow different from runpf. Kindly refer to the manual for about three different distribution power flow algorithm and how they are invoked. Lastly, not all reconfigured topology may necessarily converged even with distribution power flow algorithm. So, be sure while implementing the reconfiguration, you don't create Island.. Hope this helps. Regards.
