Yes - I wouldn't say it's automatic. I said you can apply for a 3 year visa here, not that it will necessarily be granted: I've heard of PRs getting 3 years straight away and others only being given 1 year despite having had several previous visas. It may also be that being (or not) an actual HK resident (rather than simply a HK PID holder) makes a difference, as may the passport that you hold. But that's just guesswork on my part.
