If you want to be ultra safe you can scrim all screw heads as well as the joints, bit over the top though.
Had a customer who was an architect make me do just that and he also wanted a 2mm joint between the boards.

Yes, I was trained this waywas told by a few old boys they used to leave a clout nails width between boards
whats the reason? Is it the same principal as lath and plaster? strengthening the joint or something?

God that's an old one. Does anyone actually do that?
I was always amazed by plasterboard 'laths', that system uses that principle and you only scrim the ceiling and internal corners. The edges of the boards are round, iirc, and they rely on the finish being pushed thru to stop the joint cracking. The end of the lath boards also have the 3mm gap and no scrim.
