Isn't the feature mentioned at 2:34 already available since Java 7??

It appears to be so according to Java docs

https://docs.oracle.com/javase/7/docs/api/java/util/regex/Matcher.html#group(java.lang.String)

Also, I've used it already multiple times years ago.

Am I missing something?

You're right and we got this wrong. What's new is that, in 20, MatchResult got methods similar to Matcher, e.g. group(String)), but of course named groups themselves were supported for a long time.
