I usually put them at least 3 finger-widths apart from eachother (about 2.5" between the outer plastic of the infusion set and out plastic of the dexcom sensor). I believe it ends up being about 3" between the canula and the dexcom sensor wires Never had a problem... I toss and turn all night and generally don't have an issue with pulling out the tubing or too many false readings on the dexcom.
I do the same thing. I sleep on my left side and put the CGM and Pump on my right side one above the other. I also use my arm and thigh do change it up with the pump.
I almost always have them on the same side, and sometimes relatively close to one another. I think they say 3 inches apart, but I've had them much closer, almost on top of each other, and never noticed a difference. I think they're just being conservative with that.
I believe the reason for the 3 inch mark, is that if the insulin concentration becomes too high (lack of absorption), then the sensor may read the interstitial fluid in that area as having too low a glucose value. YDMV
