Yeah, Aki was very strict on the students at the Garden. Have you seen his overall image? There was a famous character in real life that strongly resembles Aki, guess who!

I have another possibility: it's just a hint of how Time Compression works. Like, when it merges timelines into one, it uses something anti-clockwisely. It kind of makes sense because time normally progresses so that gotta be clockwise... to turn it back and mix something up, you gotta make it go anti-clockwise.
