Essentially, for all of the MEC connections, the VSS has created a clone of the configured port-channel to bind the actual physical connections, rather than binding them under the configured port-channel (and suffixed the port-channel number with A or B depending on which chassis was first to bind).
IOS does this when ethernet channel members cannot join the bundle due to negotiation mismatch. If the currently active elements are incompatible with a new element, the A/B interfaces are created. These are called "secondary aggregators" in IOS-speak. http://www.cisco.com/en/US/tech/tk389/tk213/technologies_configuration_examp... -- Ross Vandegrift ross@kallisti.us "If the fight gets hot, the songs get hotter.
