Does Async::Barrier wait for sub-tasks as well?

[postmodern]

Does Async::Barrier also wait for any sub-tasks or sub-sub-tasks spawned by the Async::Barrier#async task to also finish or will it only wait for when the async tasks directly spawned from the Async::Barrier object to finish?

barrier = Async::Barrier.new
concurrency = 10

Async do
  concurrency.times do
    barrier.async do |task|
      # do stuff
      
      task.async do |subtask|
        # splinter off and do other stuff
      end
      
      # do stuff
    end
  end
  
  barrier.wait
  # all tasks have finished(?)
end

No it only waits for tasks that are started using Barrier#async.
