In this case I would just tile slightly onto the drywall. This will be the easiest way to make sure you have a nice looking edge where your drywall and tile meet. I always use a liquid waterproofing membrane on the tile backer anyway and you can put some on the drywall where it will have tile on it. Tape the seams with some fibatape and paint over the entire area that will be
getting wet with the waterproofing. If you are using a shower pan liner on the floor make sure it goes up at least a foot on all sides and make sure the tile backer comes down over the top of it. You should be good to go. This is the way I usually do it anyway.
