Yes, really. As an IBSS station you are responsible for attempting to send 10 beacons every second (including randomized backoff timer), but cancelling each one if you hear another beacon beforehand. Therefore in a nice RF environment, one person is the beacon sender sending 10 beacons every second (the station with the fastest clock) and the others continually cancel their own beacon transmissions just before they are about to transmit their own. When the beaconing station goes away, in theory the person with the 2nd fastest running clock sends a beacon and then continues. the other stations in the set hear that and keep synchronized.
