try/catch/finally is also considered control flow and it's not conditional, although, unfortunately I've seen people use it as a control flow mechanism.
interrupts are also control flow but, again, there are no conditionals there.
control flow is about the order of execution, one common way to get there is using conditionals, but it's not the only way.
Having said that, even if you disagree with Andrew's wording, the overarching idea remains. You always know explicitly if the flow changes.
