Incorrect example given for executing critical sections of Durable entities

[ashgit24]

Hi Its mentioned in the critical section rules that "Critical sections can signal only entities they haven't locked." but in the example given, the below lines would fail to execute inside the lock. await sourceProxy.Add(-transferAmount); await destinationProxy.Add(transferAmount);

using (await context.LockAsync(sourceEntity, destinationEntity))
{
    ICounter sourceProxy = 
        context.CreateEntityProxy<ICounter>(sourceEntity);
    ICounter destinationProxy =
        context.CreateEntityProxy<ICounter>(destinationEntity);

    int sourceBalance = await sourceProxy.Get();

    if (sourceBalance >= transferAmount)
    {
        await sourceProxy.Add(-transferAmount);
        await destinationProxy.Add(transferAmount);

        // the transfer succeeded
        return true;
    }
    else
    {
        // the transfer failed due to insufficient funds
        return false;
   }
