Garden Party Notches for larger sizes

I checked the forum first to see if anyone else had this issue but could not find anything, so maybe it's me (sewing at 1am). ;) I am in the middle of sewing the Garden Party blouse in size 12 using some pretty Liberty Lawn I picked up on sale recently.  The illustration on page 2, bottom of column 4 shows the front skirt pattern with 2 notches at the top on each side with the corresponding 2 dots centered between the notches across the waist. However, the pattern has the dots spaced a half inch above the stitching line. However, on page 3, columns 1 and 2 show 3 notches on that section with the waistband centered between the bottom two notches (column 2), with the 3rd set of notches towards the top of both sides above the waistband.  Yet, when I double-checked the pattern piece there are only two notches with the two dots in line with the top of those two side notches.   My question, therefore, begins with the instructions on page 2, column 4.  Where do I start stitching that first line of basting stitches?  On the line?  Or starting at the dots (drawing a line between them?) and sewing between those dots first (then stitching 3/8 inch on either side of that)? Hoping this is a clear explanation. Am I missing something? Thanks so much for your time on this.
