Exactly that. I had to read it twice too. The way I read it is there were so many hearings so quickly in a row that the judge was in some sort of blur. Case, bam, verdict. Case, bam, verdict. One every 10 minutes. And in that situation, just from being asked to think it over a few more seconds, she saw that maybe she had it wrong and changed her mind.
My reading was that the judge had thirty seconds to regard the grieving family and changed her mind and asking her to reconsider gave her an easy opportunity to change the sentence.
