Custom RTMP Live Stream Redirect

Hi.

Can someone confirm that if you have a live stream set up with a custom RTMP and you reach webinar capacity, it will NOT redirect users to the livestream link, even if you have that option enabled? But it will if you use one of the other services (Facebook, YouTube, etc..).  This is in reference to the "Remind users to watch the live stream (doesn't apply to custom RTMP)" option. And maybe why that's the case?

Thanks
