Can VARIOUS IntentServices work in parallel?

Question

It’s hard for me to understand one rule about IntentServices.

From Creating a Background Service :

Work requests are executed sequentially. If an operation is performed in the IntentService and you send it another request, the request waits for the completion of the first operation.

I do not understand if this implies different calls to SAME IntentService or even to different IntentServices.

Help will be appreciated.
