Hardibacker --> Drywall transitions

I'm getting ready to tile my shower surround. It's a standard surround wall, 60x30. I'm accustomed to Hardibacker as that is what I have used in the last bathroom I tiled (about 10 years back). I came across something I wanted to share and ask what your thoughts were. This person says they like to hide Hardi --> Drywall transitions under tile, and they say they do it like this:

I strongly suggest that you hide backer to drywall transitions under tile. When I do a normal tub surround I buy 4 pieces of backer. One goes up vertical on each side (5 feet), one horizontal on the back, and another cut at 2 feet horizontal so that we have 5 feet above tub deck all the way around. Drywall above that . I even do the drywall if tiling to the ceiling. Then the tile is going to at least 5 1/2 feet above the deck and 3 1/2 feet from the wall. No transitions for me.
That actually sounds pretty good to me but I'm going to be tiling all the way to my ceiling (8') and I'm apprehensive about attaching thinset and tiles to the drywall.

Your seam between drywall and backer board should be very close to the tile edge, but just under the tile. You finish that butt joint with durabond and tape (such as Fibafuse) and then skim coat it with an easy sand setting compound. Tile on drywall is fine as long as it is not in a wet location. (Inside the shower).
