While having a pointed pick is strictly up to your taste, and in no way reflects on the tool's effectiveness, it's all in the way you use the pick.
As mentioned above; if you press a pick up into the pin chambers, forcing the pins deeper than a key-blank would raise them, then you will over compress and weaken the springs in those chambers. This will result in sluggish "jiggling" movement of the pins, because they are not pushed down with as much force as originally designed and may get stuck on their way down.
A very pointy pick will allow this to happen than a blunt point pick, but that shouldn't discourage you from using the tool. Rather, be more careful with how far you push the pins up, remembering that they should never go higher than a key-blank would push them. In fact, a pointy pick may give you better feedback as to the location of the pins, because you can feel the edges and tips of the pins more easily. Just don't push too high.
