AFAIK, the two things are orthogonal. My understanding was he'd already kickstarted a normal recovery process https://accounts.google.com/signin/recovery And he wanted more details, so I assume he spoke to somebody up the escalation chain in our support org, who gave him more details.
that's not what https://www.inc.com/sonya-mann/salil-mehta-free-speech.html says about it. "Mehta was lucky. The public outcry and press attention prompted Google to manually review his case."

I know it sucks, but account security is tough, and I have nothing but respect for the hardworking people that handle that. In my second week at Google, I accidentally typed my password into a non-secure (but still legitimate) web-form. Within minutes, I got an alert asking me to change my password immediately. They take security very seriously.
