The projectors are designed this way. The sharp cutoff is less glaring to oncoming traffic.
In fact, standard non projector halogen reflectors and lenses are designed to give you the same sort of beam cut off, but the optics have never been as good as projectors, so you get the sort of bleed over and not the sharp cut off that projectors give. I do agree, however, that the sharp cut off is hard to get used to and the lack of bleed over takes some getting used to. Projectors, whether halogen or HID throw a lot more focused light out than the traditional reflectors, so I think the cut off is almost mandatory.
Do be careful on adjustments. In my old car which had AFS HIDs, people were experiencing the same discomfort with the cut off and adjusted upwards. Some over adjusted, going past the limits and $1500 later were the proud owners of replacement AFS HID projector units.
