I'm wondering if this is the same thing I've been hearing about, or something different.

What I've being hearing is that USGBC would be collecting up CIRs that they consider precedent-setting, and boiling them down to the key points that are applicable to other projects, and publishing these on a monthly basis, or thereabouts, as "LEED Interpretations." This has not yet happened for LEED 2009, but I've heard that we could expect the first bath pretty soon.

This has some similarities with what you've heard, but also some key differences. Interesting....
