Watch the video you will see the guy switch directions. He is avoiding the powder measure. You will also see him hesitate due to a sticky primer slide.
Personally, I've learned to live with it and it's not a huge problem. For rifles I have the Powder measure off anyway. I ike to throw the charge light then trickle up. For pistol I slam them out and check every tenth charge or so. The RCBS powder measure is incredibally accurate with the powders I use.
