Welcome ZZIP to the Board!!! You can be curious all you want zzip, but your great question is not being answered because I don't think the poster has a reply since it is against logic.
zzip: BTW Welcome to the IHUB!! I agree, why did he dump 60mm at .0001 when he could have held for .0002 or beyond? Maybe he panicked. Who knows? Hopefully he will answer you on that point.
