They aren't lying, but their methods are still dangerous despite their implying the contrary. Their approach requires perfection on both the submitter and reviewer.

The submitter has to remember to send the "warning, don't apply patch" mail in the short time window between confirmation and merging. What happens if one of the students doing this work gets sick and misses some days of work, withdraws from the program, just completely forgets to send the mail?

What if the reviewer doesn't see the mail in time or it goes to spam?
