Sounds about right; when the pads cool, they become more abrasive, and probably cleaned the disc surface of uneven deposits. Or, your pads may have cooled to its ideal temperature range and laid an even layer of deposit all around the disc, while also spreading the existing uneven deposits evenly around the discs.
