Submitting for an internal review a day before the deadline is not a common thing in Google Research at all. I worked there and actually was not able to submit a paper to an external conference because the internal deadline was only 3 days away and it was likely we wouldn't be able to get the internal approval ahead of time. The rules were clear and as far as I understood it, people did follow them. If there was any selective enforcement, it would be in her favor if she expected a single day to be enough.
