Yeah, that's a good case to be aware of. I do mention it in the book while discussing anchors (indicating alternatives have their own independent anchors) [0]

Yeah, that's a good case to be aware of. I do mention it in the book while discussing anchors (indicating alternatives have their own independent anchors) [0] and grouping [1]. I also discuss how `re.fullmatch` is useful, especially when constructing an alternation pattern from a list of terms. Easier to use fullmatch instead of manually adding a group and string anchors.
