When you already run a startup like we do, you do not have much time to submit, you code, so the deadline sneaks up on you. I would say you can not read much into the submission date.
I don't think you understand his point. He's not just looking at the submission time of the application. He talks to the applicants, and some of them say they didn't decide to apply until the last day. This is different from deciding to apply weeks before the deadline, but not doing it until the last day.
