I was out bouldering the other day and say some guys dipping their brushes into their chalk before they scrubbed the holds. Do any of you do this? Seems to negate the purpose of brushing to me but I don’t know much.

I don’t. I agree it doesn’t seem like a good idea (unless the rock is damp?). I would think the ideal friction situation would be completely clean rock and dry hands. I’ve occasionally added extra chalk to a hold in an effort to make a hold less sharp, but I t’s not very effective.
I do it for plastic holds that have just been cleaned (they tend to suck all of the chalk off of your hands otherwise). I may have also done it for damp/greasy holds outdoors, but not in an area where chalk on holds is a real concern.
I do it occasionally. That occasion is when I can literally see grease spots on the rock and/or it's hot out. Dipping the brush in the chalk gets a small amount in the bristles. Tap it on the damp/greasy spot, rub with a finger, then brush off and it brushes the layer off entirely. There is some very slick, non porous rock (volcanic tuff or conglomerate) locally that seems to get dark black moisture spots on it that build up and get slick over time. It's just a way of cleaning these off.
