I completely agree with this. If you're having trouble coming up with a visual, try this...fold your fabric selvage to selvage and hold it in the air - you'll likely see a 'bubble' at the fold line. That 'bubble' is what is creating your 'v' when you cut. Lay that piece of fabric flat on your table and smooth out the bubble. I'm fortunate that I have a large enough cutting surface to not have to fold again. If you must, just repeat that process.
