Yes, but why should that matter given that you don’t care when future{1,2} are
actually executed?

The Future API also supports sequencing operations, which seem more appropriate
to use in this case:
val future3 = future1.andThen(agent.send(1)).flatMap(_ =>
future2).andThen(agent.send(2))
future3 completes with the value of future2, but only after the second
agent.send() has been executed.
