Yes, but the point the parent comment is referring to is that Google (apparently) abandoned Microsoft Windows completely - across the entire company. Even admin staff, accounts staff, the computers used to book free massages etc.
Some how I doubted it (how would they QA test any of their Windows executables such as Chrome or GTalk) but it was what they announced.
Essentially what happened was you had to have a manager approved justification for running a windows machine, whereas previously it was left entirely up to user choice.
Google also has a habit of releasing information to the public as if it's current, whereas it's actually what they were doing a few years previously. I wouldn't be surprised if that video segment was three or four years old.
