I believe it's true, 100%. We as people tend to do really dumb things because of the sense of urgency - it's tied to panicking, being emotional or just being impatient.
If you first use your brain to think about what to do in a situation optimally, and then use your energy to do just that, you'll use it way more wisely (as you said) which leads to better energy management.
I also think people think too much about rationing their energy when they should be thinking about how to increase their energy - food and sleep being 2 baselines. But that's an entirely different topic :Funny:
Forgive me if I understood what you said wrong.
