It's more like without a code review you can only commit to your personal scratch space.
A more accurate way to state "At Google, no code, for any product, for any project, gets checked in until it gets a positive review" would be that "No code goes into production without a positive code review."
The original statement makes sense if they are not using a DVCS (I know that at least a couple years ago they were mostly a Perforce shop). If they are now using a DVCS then they probably have repos for different code stages plus all the local repos.

Which is completely reasonable. The original contention of no checkins at all sounds like hell.
