I think he meant the symbolic gesture of defecting rather than opening fire on fellow citizens.
The Syrian military is supposedly fiercely behind Al Assad and against the rebellion, but this could be a sign of a growing resentment amongst its ranks and possibly of a loss of confidence in the regime.
Defecting is never an easy decision, but I think an army should never, ever, be used against the people it is supposed to protect and serve, and it's especially vile in the case of a dictator using it to fight for his power and against democracy.
