Why not?
Even though, I assume the deadline is the deadline, and that was Dec 21, 2012 @ 11:00 Pacific Time.
If the NR recommends to continue voting white, then the Green side (as Mimi also said) should continue to vote Green. It only shows more & more support up to & including the time of the AGM. Why Not show support if you believe in the side of change, and you were unable to get your votes complete in time. Vote anyway, show your support!
