Productivity is output per hour worked, yes. What happened at the start of Covid is that many of the jobs with bounded output (services, food etc) shutdown, leaving the white-collar work which is less bounded. Less hours worked but most of the money made implies that productivity would increase. The same thing happened in reverse in 2021. Not complicated, but for whatever reason this isn't obvious to people.
