Atlas deviceSync Subscription and MongoDb Connections, how to count?

The following code is generating about 30 some odd connections on the Primary MongoDB instance. How does the deviceSync subscription and mongoDB instance connection correlate?

1 subscribe = ~30 connections?

    let fetchResult = try? await syncedRealm
        .objects(SUPER_COOOL_TYPE.self)
        .where({ $0.value == value })
        .subscribe(waitForSync: .always)
    
    guard let result = fetchResult else {
        return
    }
    
    try? await syncedRealm.asyncWrite({
        // do some work
        switch (input, output) {
        case (.some, .some(let outValue)):
            syncedRealm.add(outValue)
        case (.some(let inValue), .none):
            syncedRealm.delete(inValue)
        default:
            break
        }
    })
    result.unsubscribe()
