Agreed.

Fortunately, it isn't meant to be a "trendline", but instead a measure to show that correlation between exchanges does not exist anymore.

Different exchanges are supposed to have correlations near 1.00. (.99 to .95 is to be expected) However, with correlations near .5, it is clear that Bitstamp prices are very different from Mt. Gox prices.
