This is more or less correct.  If an article just misses the threshold  
on one pipeline run, it can take about three weeks for it to get  
created.

Of course, the latency for most articles is much less than this.

No.  All that matters is if the article was created in the two days  
before the pipeline run.  "Touched" is a bit of a misnomer.
