I'll second that.
I think "using flaps as speedbrake" more applies to extending flaps (and say, flying 220kts with flaps 5 and speedbrakes retracted), when you really should have been using the speedbrake first, and only then adding drag if speedbrakes aren't enough to get you back on profile/speed.
