Makes sense. To clarify: The only one who truly used a bunch of abilities at the same time was Edo Nagato. So it's possible, but i think Sasuke wasn't at that level yet. And activating Deva Path to fly would take effort towards actual flight, preventing him from using other techniques.

But he only uses Deva for the first time when he seals the Biju, so it's likely that he wasn't able to use it before.
