My understanding from Chasak was style switching was purely for beta to allow monk testers the ability to switch and test all styles.

HI guys first post. During Beta, we had the opportunity to switch styles (Dragon, Harmonious, Drunken). When you switched there was a bug that allowed you to keep and use alot of your previous styles abilities. So if you started with drunken and went harmonious you might still have some drunken style abilities available. However when meditating using the AUM skill you would only receive skills applicable to your current style.
I believe in the release game once you pick your style at 15 you are set. Shamans also pick their patron at 15 and there is no going back after that. So choose wisely. After 15 you will still get general skills(disciplines) of all styles but will only receive specialized (Mastery/Aum abilities) skills from your chosen style.
