Note that all digits in d are restricted to one unit - if one is missing, all others must be true (like in an ALS).

Lovely! Even though not every cell in the d unit shares a sector with every other cell, each candidate shares a sector with all other examples of that candidate, so no candidate can appear twice in the unit. Eliminate one of the seven candidates and all the other six must be true.
There's been some discussion lately about ALS/AALS terminology, so we probably agree that the d unit shouldn't be called an ALS since not all cells are in the same sector. What should it be called?
