They're saying that by putting a Blaze Rod in a Macerator, it gives you 5 Blaze Powder (4 Blaze Powder and possibly 1 Sulfur if you put the rod in a Pulverizer), and that by using 2 Blaze Powder and a Minium Stone, you can craft a Blaze Rod. So you get 2 Blaze Rods and a Blaze Powder by Macerating 1 Blaze Rod.

The same goes for Bones. Pulverizing a bone gives you six Bone Meal, and three Bone Meal with the Minium Stone gives you another Bone, essentially doubling your Bone supply.
