4 overlapping cuts? What do you mean?
Look back at the video. Now make a cut 1/4 way around. Make another cut just below it 1/4 way around. Make another cut just above it 1/4 way around and the last one 1/4 just below for the last one.
What you have is 4 cuts all the way around with 4 pieces evenly spaced holding it together. You will still get the separation needed to make it act like a slug but there are still 4 places that the shell is being held together.
If you make only one cut then the shell will separate and cock to one side as you pull it out of the mag. In a pump you control how the shell ejects and loads. I have not tried it but the sharp action of an auto would just rip it apart. I have torn the metal off the bottom of some shells with my auto.
The trick is to get the plastic to give and send the "slug" downrange without enough pressure to open the front petals. The 4 cuts keep it all in one piece and "straight" coming out of the mag and into the chamber.
Hope this helps.
