No, I'm talking about the week or two after the final recall was announced.in mid October. All the daily reports of fires suddenly ended after speculation Samsung would make an announcement on Oct 9 and then they subsequently officially announced I think on the 13th. There is no way the majority of phones were returned during those 2 weeks and there were reports before November about how well more than half in the US were still not returned. I personally did not return mine until November since I was traveling. The stories of Note7 fires stopped or were diminished greatly well before the "As of November 5th" date.
Ok, I don't have the statements from Samsung you're referencing, but on November 5th they announced that more than 85% of the Note 7's had been turned in and the two numbers given for phones in the US were less than 40,000 and less than 50,000 still in the wild. Given that was 4 weeks ago, the number is probably much smaller by now.
October 9th is on or about the day that the carriers stopped selling them and was when the recall was initiated. At that time there were around 300,000 Note 7's in the wild so it's obviously not only possible, but incredibly likely that between 10/9 and 11/5 it'd be very easy to have 250,000 of them turned in during that 4 week period.
This is given that in the period between the first recall (9/2) and just 8 days after they resumed sales (9/21) in the US on 9/29, over 95% of Note 7 devices in the US from the original recall were returned, which was over 425,000 devices in 4 weeks.
