Okay, I've listened and read but can't find any reference to this being manual. A bit of help, please.
The direct quote from Matt's twitter account was "We just started a new ranking update today for some spammy queries. See 2:30-3:10 of this video".
Speaking for myself, I'm reading "Some Spammy Queries" as a manually selected list, which gets treated differently than everything else. Watching the portion of the video he refers to reinforces that thought for me. He's vague enough, however, that there's room for different interpretations.
