How to eliminate a circular dependency?

I added the following column to a table named 'User Story'.  It uses a relationship that is disabled because it is redundant and only useful for this particular set of calculations.  The values calculated for each row are correct.

Count of Failing Tests = 
  COUNTROWS (
    CALCULATETABLE (
      'Test Case Most Recent Result',
      USERELATIONSHIP ('User Story'[WorkItemId], '_Relation'[WorkItemId]),
      'Test Case Most Recent Result'[Outcome] = "Failed"
    )
  )


The problem comes when I add a nearly identical column.  The only difference is that instead of results with an outcome of "Failed", I want to calculate the ones with an outcome of "Passed." 

Count of Passing Tests = 
  COUNTROWS (
    CALCULATETABLE (
      'Test Case Most Recent Result',
      USERELATIONSHIP ('User Story'[WorkItemId], '_Relation'[WorkItemId]),
      'Test Case Most Recent Result'[Outcome] = "Passed"
    )
  )


When I try to add this column, I get the following message about circular dependencies.

A circular dependency was detected: User Story[Count of Passing Tests], User Story[Count of Failing Tests], User Story[Count of Passing Tests].


How is this circular?  Is there a general pattern for counting the rows in a related table, specifying both a relationship and a filter? Any help is greatly appreciated.
