Nice, most of my wardii - I currently have 3 different clones, usually bloom with 1 flower, but when they get up to multigrowth plants I have seen the same plants put out 2 flowers. Its not unusual, a sign of good health. Keep on doing what ever you are doing. Well done.
The flowers will be more 'formal' looking, and a bit larger when there is only one flower. That second bud does draw energy away from the first bud.
