I got some snipe regularly when I first got mine and adjusted the beds forever without really removing it. Keep the cut quite small basically prevents it, but when I threw some 1/4" red oak in the other day (which was not flat at all) I got snipe again at the trail end (not at the lead end).
Short story is - I think it's a fact of line, but you should be able to live with it if you limit the depth of cut. If you're still getting some with tables properly adjusted, flat boards and a shallow cut, that suggests something's not right.
