Q: In the “Dynamically fixing orphaned words with GREP” tutorial the author uses the term:
(?<=\w)\s(?=\w+[[:punct:]]+$)
In an earlier course the author described the + (one or more) modifier as unusable in a lookbehind or lookahead i.e. (?<=.+). What's the difference here?

A: The limitation mentioned in an earlier movie referred only to positive lookbehind and negative lookbehind. I was able to use the one or more times (+) metacharacter in the positive lookahead portion of the expression because that limitation doesn't affect either positive or negative lookahead. It's only when looking backward that GREP ignores the repeat metacharacters.
