Don't you lock up something that you wanted to see fly

My jukido jujitsu instructor was doing this exercise where we go around inside a circle putting in light strikes until we're all around the circle. He said we could use any strikes that we were taught. When it got to my turn, he explicitly told me, "No back kicks, spin kicks, or any other crazy stuff. We didn't teach you that." Of course, in his demo, he used back kicks. Then I asked him, "How did you know I planned to use back kicks?" He said, "I could see it in your eyes." What really ticks me off is that I practice back kicks and spin kicks in my free time, and I'm pretty good at them, better than the instructor. It would've been nice if he could've seen them.
