No, it's not lengthened ones. They use ô for *au consistently. (Since /ō/ corresponds to later Saxon /ou/ and contemporary Dutch/German /uo/.) So maybe the circumflex means 'no diphthong'. I cannot speak for 'ê', though. But I consider it good practice, since a proper Old Saxon declaration makes it easer to reconstruct whether later people said /hø:ved/, /hœ:ved/ or /hœʏved/.
