I don't really know about PL, but creepy crawlies go up my spine when I hear a "quilt" called a "blanket". Jeez! A "pot" is not a "skillet" even though it is a cooking utensil, and a "car" is not a "truck" even though it is a motor vehicle. I realize that the differences might seem minor to some, and it might just be semantics, but if I'm a little bit OCD, that's fine, just call it what it is.
