OpenJDK LTS Releases

I've been sifting through information about the changes to the Java release cycle and it seems that there is conflicting information about LTS releases of the OpenJDK. In the YouTube video, "Moving Java Forward Faster by Mark Reinhold & Brian Goetz" [1], Mark puts up a slide at time 06:10 or so that shows that OpenJDK releases of Java 11 and 17 will be LTS releases that last 3 years. However, in the more recent video, "Changes to the JDK Release Model with Sharat Chander" [2], a slide is put up at time 20:36 or so that shows the _Oracle_ JDK releases of 11 and 17 as getting 3 years of support but that the OpenJDK releases of 11 and 17 are only supported for 6 months. 

So, what exactly constitutes a Long Term Support Release in the context of the OpenJDK? Does the OpenJDK project intend to release regular security updates of the OpenJDK LTS releases (11, 17, etc.)? Or did I misunderstand that from Mark's original video. I also see that Oracle is sponsoring builds of the OpenJDK for Linux, Mac and Win64. Will these binaries be available for LTS releases and their subsequent security updates or are they only available during the 6 month feature release cycle?

Thanks in advance for your help! I'm just trying to wrap my head around these changes to ensure that my company does the right thing.
