I have been told by a dentist that the reason for "you must brush your teeth for 2 minutes" is mostly because the tooth paste should have time to work on the teeth. I.e. Not to remove physical "dirt". In which case you should keep the paste on for two minutes even with this device.
Disclaimer: I never checked on the 2 min fact, but do think a dentist would know.
