I wouldn't recommend doing this at all. The foam loosens the dirt/dust/pollen, and will help get some (if it's dirt or road film) or most (if it's dust or pollen and the car hasn't gotten wet at all with that on there) of it off. However, even in the best case it's unlikely that it's leaving a clean enough surface to dry without putting swirls/scratches in the paint.
The goal is to have the cleanest possible surface before using the two-bucket wash. Spraying your car down first would be the most basic; soaking with a foam gun, waiting a few minutes and rinsing would be the next; and soaking with a foam cannon the best. After any of these, you would still want to follow with a very soapy two-bucket wash and rinse down before drying with a MF towel; many also use a spray detailer to help lubricate the surface while drying.
Two months ago this would have been overkill for me, but now with the fresh swirl-free paint I will be doing my best to keep it that way!!
