I was an Oracle employee that was laid off in the March wave. That’s exactly how it worked.

6am email. You were an employee through any notification/WARN period. But no access. No work. Garden leave euphemistically.

WARN varies by state and location. And usually is only applied to onsite employees. And only if the layoff affects certain number or more. So if you are a remote employee, you were done at the next pay period. For me in CO that was 4/10. Not 60 days obviously as I didn’t qualify for a WARN notice due to being remote.

Various CA colleagues were through May or close to that.
