No, the herb has to be completely covered by the menstruum (it can just barely cover it, but it must be covered), not all fresh herbs can be tinctured at a 1:2 ratio, some need 1:2.25, 1:2.5 or 1:3. It is not an issue of over grinding, under grinding is often more of an issue. I do not know exactly what Kerry told you , so I cannot say if there was some error in her directions, I can say that if you do not account for the water in the herb, you will reduce your alcohol percentage sometimes to the point where you either have an unstable tincture or an ineffective one.
