It looks to me like she wants you to start from the tip of the outside (olive green) triangle each time. I'm not sure, but I think when she says to jog them slightly she might mean to make sure that you allow for the 1/4" seam allowance when you align the edges. If you look at the circled parts, the base of the olive green triangle and the tip of the aqua triangle do not line up exactly along the edge that is perpendicular to the seam line. If you have them properly aligned, then there will be a slight overhang and you will have a sort of v intersection that will measure 1/4" (scant) from the edge (on the seam line side) to where they overlap. See the center picture where the circle shows the two olive green edges coming together. Now look at the red stitch line and see how it comes out in the notch (or V) where the two overlap. That is what will give you the 1/4" allowance so that your point doesn't get chopped off when you put the block into the quilt.
Hope that helps.
