how am I supposed to feel pressure on my heel while carving

I've been watching a bunch of youtube videos on carving, and I heard that you are supposed to start the carve with pressure on your toes, then, midway through, shift it to your heels. How am I supposed to get my weight onto my heels? I've tried "pulling" my skis forward so that there's more weight on the tails, but idk if this is correct.

tl;dr
1: How do I feel the pressure on my heels while carving
2: Is my method of "pulling" my skis (for more pressure on my heel/tails) correct

also, this is the video I've watched: https://www.youtube.com/watch?v=6sdEFYz7i2g&list=WL
