I think the refference to the Hamilton and Raikonnen issue is because of the inconcistency of stewarding at the FIA. Personally I feel Hamilton was being penalised at any given opportunity at that time and with harsh penalties and the FIA even admitted afterwards that was the case and that they had been issuing penalties deliberately as part of the concorde agreement with Ferrari, so it's kind of moot point now to debate it now.
I'm actually glad that common sense and reason has to some small degree crept in and Button was given the opportunity to right the situation, even though - technically - he did not return the place before the following corner and should have had a more severe penalty.
I dislike the way penalties are shaping the championship whilst the decisions and punishments are so erratic, and hopefully the decision made regards Button (where the stewards communicated to BAR and gave them the chance to correct the situation) will be the precedent for the future.
