They mean 30 degrees from horizonal, or compared to the cutting surface. You want to hold the lame parallel to the surface and then lift the edge that’s further from the loaf by about 30 degrees.

It also helps to start the cut with the corner of the lame. I personally got better ears by going in a second time to reinforce the same cuts.
