Why PauseWorkoutSession of Health store not pausing the Session?

I am creating an iWatch app which reads HeartRate data which I then use to plot some graphs. There are 2 buttons in the app, one to pause the workout session and other to resume the workout session. On click of Pause button, I am calling pauseWorkoutSession method of healthStore: 

healthStore.pauseWorkoutSession(workoutSession!)

OnClick of Resume Button, I am calling resumeWorkoutSession method of healthStore:

healthStore.resumeWorkoutSession(workoutSession!)

To get HeartRate data, I am running the following code:

let quantityType = HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeartRate)!
            let datePredicate = HKQuery.predicateForSamplesWithStartDate(instanceDel.workoutSessionStartDate, endDate: nil, options: .StrictStartDate)


            let updateHandler: (HKAnchoredObjectQuery,[HKSample]?,[HKDeletedObject]?,HKQueryAnchor?,
                NSError?)-> Void  = {query, samples, deleteObjects, newAnchor, error  in

                    if !self.instanceDel.workoutPaused {
                        //do something 
                    }
            }

heartRateQuery = HKAnchoredObjectQuery(type: quantityType, predicate: datePredicate, anchor: nil, limit: Int(HKObjectQueryNoLimit) , resultsHandler: updateHandler)            
heartRateQuery!.updateHandler = updateHandler
instanceDel.healthStore.executeQuery(heartRateQuery!)

The problem I am facing is that update handler is continuously called and new heart rate values are are continuously added to samples array even when workout is paused. What does pauseWorkoutSession exactly does? Isn' t it suppose to pause the workout session so that new new heart rate reading come?

Pausing a workout isn't intended to prevent heart rate samples or any other type of samples from being collected by watchOS. Think about it this way - even when the watch is not recording a workout, it is still collecting heart rate, steps, distance, calories, etc.

If you want to ignore samples that are recorded while your session is paused, you should stop the query or ignore the samples.
