The 2019 edition of 13 has been changed to (*the red bold highlighted text has been deleted*):
9.3.14.3 - Where there is a noncombustible space above a noncombustible or limited-combustible drop ceiling that is sprinklered because it is open to an adjacent sprinklered space *on only one side *and where there is no possibility for storage above the drop ceiling, the sprinkler system shall be permitted to extend only as far into the space as 0.6 times the square root of the design area of the sprinkler system in the adjacent space. I will see if the section is open in the 2022 edition process and see if we can add something to the annex. Hope this helps.
