Page filters ignored by report measure?

I’ve figured it out with a little more creative searching and also taking the mantra ‘the measure is the treasure’ to heart. With the guidance from Iterate though issue level filtering by Pages, I updated it like so and it works (also changed Count to Sum in the process and can’t be bothered to go back):

Sum(
  Filter(
    [Issue].Members,
    [Measures].[Issues created] > 0
  ),
  IIf(
    NOT IsEmpty(<measure that returns field name>),
    1, 0
  )
)
