2pass is VBR too... If you do two different CRF (assuming that in the second time you've hit your bitrate/filesize target) you have spent more time than a single "2pass" encode. And the result is nearly identical. Please note that the 1st analysis pass of a 2pass encode takes less time than a regular 'encoding' pass (unless you use --slow-firstpass).
