Good on you for pointing out they 4peated, but as I already explained, this happened before Collingwood became a perennial Grand Final failure which saw them also lose the 2011 GF. So it's just not relevant to Collingwood's current Grand Final record.
If you ever needed more proof that these records matter, only take a look at the 2010 Grand Final. Two GF losers collide, it's not a coincidence it was a draw
