Yes, it's intended. Piotr identified the code that does this. If the
shell is currently interactive, it can't be sure under what circumstances
it's printing a job notification. If it's doing asynchronous notification,
it puts the \r in there to make the output look better. A process in a
pipeline is not currently interactive, so bash doesn't do that in the
second case.
