The pointer on this ToApprove template points to the current Approved version of the article (May 12, 2009) and I assumed that it is meant for the latest version of the Draft which made it's last edits on June 18, 2009 by Robert. I also see that Gareth and Supten added their endorsement on June 19th and 20th which I also assume means that they saw the last two edits that were made after June 1, 2009 which is the date on the template. Considering that Robert made the edits, it looks like we have three editors that endorse the June 18, 2009 version, there were no objections so the June 18th version was used as the re-approval version.
