The bolding of material including and inside "[]" is done by the aggregator site, and is emphatically NOT part of the original, at least in this specific instance.

Okay, thanks! I wonder why they did that. Sure muddies the waters if you don't go back to the original.

I think just to draw attention for ease of searching for "patterns in the killboxes."

Just above is a remark to the effect that simply being inside square brackets is emphasis.

Occasionally, the limited context provided by the aggregator sites results in speculation beyond what (or far afield from) the full context actually suggests. Other than wasted time running down blind alleys, this weakness in aggregator presentation is not a problem.
