Ditra membrane confusion

Now I would have done the same as the OP!
Strengthened the floorboards with plywood and covered with ditra for an uncoupling membrane and fully waterproofed subfloor.

Not sure why the ditra isn’t a good add. I agree the cement board is far better than ply. If it’s an option I would remove the floorboards and place a 22mm cement board down and then ditra and tile. Thoughts?
