When using matches(), you are asking if the string you provided matches your regex as a whole. It is as if you added ^ at the beginning of your regex and $ at the end.
Your regex is otherwise fine, and returns what you expect. I recommend testing it regexplanet.com, Java mode. You will see when matches() is true, when it false, and what each find() will return.
To solve your problem, I think you only need to remove the if (matcher.matches()) condition.

Does this tool use the Java regex engine?
This tool runs in the browser using the JavaScript regex engine, which is similar to Java but has some differences. Possessive quantifiers (*+, ++), atomic groups (?>...), and some Unicode properties (\p{IsGreek}) work in Java but not in JavaScript. Always verify critical patterns in a Java runtime.
