A flow state by definition is when you only focus on the thing you are currently working on. I would say this is quite the opposite. You are busy with something else, but your mind subconsciously continues to think about the problem. Just like when you suddenly think of the solution for a problem, while standing under the shower. Sometimes you just need to get away from the problem to solve it.
