Good job, Sherill, in following through on this concern of yours. I imagine that Pamela is grateful that you pointed out the discrepancy for her. I know Sandra Betzina has talked often about all that goes on between her final drafted pattern and what ultimately gets stuffed into the pattern envelope, so the error could have occurred anywhere along the way, I would think.
You provided a nice service to others who will be using this pattern and to the pattern author as well. You deserve an extra large pat on the back for being so helpful!
