Should it not just do what the 2nd commands ouput does when it reaches onCPU=400, and exit afterwards rather than create a new time quantum?

Whenever a process moved from READY->RUNNING it gets a new timequantum. In your 1st example, this is reported when the process's transition is complete, and the process is now able to (continue) executing. In your 2nd example, the process is already running on the CPU, calculating something, and so doesn't get a new timequantum.
