Cron's failure mode is silence. A wrong expression does not error. It just runs at a time you did not expect, or never runs at all, and you find out days later. The next-run preview is the whole point. It turns an abstract expression into ten concrete timestamps you can check against what you meant.
The field that catches people is day-of-month combined with day-of-week. In standard cron, setting both means OR, not AND: 0 0 1 * 1 fires on the first of the month and every Monday, which is almost never what anyone intends. The preview makes that obvious immediately.
