Is the intent of the obstruction against walls (Figure 22.214.171.124.2(b)) to require soffits over 30" to be protected below even if the criteria in 126.96.36.199.2(a) is met?
Which edition of 13?
Commentary says if not over 30 inches, and sprinklers are positioned in front of the obstruction as shown in the figure, additional sprinklers can be omitted.
I would say yes over 30, but I am thinking another rule could apply, like (c) or something else.
Or, Say if the sprinkler is 7'6" off the actual wall, it might be far enough back. Or if you are in a small room rule, and the sprinkler could be 9' off one wall, and you chose the obstruction wall.
That section might be used, if you had to have a sprinkler close to the obstruction.
