The new PowerToys are out (we’re at version 0.70.0) and with it comes a new version of Awake, the caffeinate tool that folks are used to on a Mac, brought to life on Windows. This behavior was caused by the fact that for each state change in Awake a new thread would be spun up that would have a SetThreadExecutionState call done within it that would request a specific execution state combination. Instead, now you have a single thread that observes state change requests and adjusts its execution state accordingly, resulting in much smoother transitions from one state to another.
