Yes, this seems to be the norm. There has been discussion of this before, and I believe that the consensus is that the ionic silver combines with the O in the H2O2 yielding AgO and H2O, I.E. water and silver oxide. Silver oxide is virtually insoluble, so it forms a precipitate that appears milky until it can settle out.
If this is the case, it might be a good way of making 100% colloidal silver, since the ionic should settle out over time.
