No. I think you've got it backwards.
My take- without a new rule book nor state clinic yet held- is that they are saying for contact on a receiver who has not yet become a runner to be legal; 1) legal contact can be incidental going for the ball they are entitled to possess, i.e. bumping chests, shoulders, arms etc. while both going for the ball 2) legal contact may be made with open hands, or 3) legal contact may be made by wrapping one or both arms around the receiver in an attempt to tackle the receiver.
What will not be allowed are "kill shots", i.e. forcible contact with shoulder, chest, or upper arm anywhere, not just the head and neck area of the receiver. Think of blindside block parameters, minus the wrapping up with arm(s).
The NC state clinics begin on June 26 and we usually get the NFHS power point presentation along with it. I normally post the link when it is available.
