The doc string for re-matches says that it uses java.util.regex.Matcher.matches(). The Java doc page for the class java.util.regex.Matcher [1] says "The matches <https://docs.oracle.com/javase/8/docs/api/java/util/regex/Matcher.html#matches--> method attempts to match the entire input sequence against the pattern."
The doc string for re-find says that it uses java.util.regex.Matcher.find(). On [1] you can find the statement " The find <https://docs.oracle.com/javase/8/docs/api/java/util/regex/Matcher.html#find--> method scans the input sequence looking for the next subsequence that matches the pattern." I haven't dug into your regex and string in detail, but most likely what is happening is that the regex matches part of the string, but it doesn't match the _entire_ string.
