I believe that NiFi uses the Quartz cron syntax, which is described here: http://quartz-scheduler.org/api/2.2.0/org/quartz/CronExpression.html
As for why, I believe it is because NiFi uses the Quartz java library to schedule processes, so it kept with Quartz syntax rather than translating it. I'm not sure why Quartz uses 6 instead of 5. Probably for more precision so that you can schedule down to the second if you want to.
