The Platforms section displays the device on which the crash occurs, rather than at the API level. However, as you saw, it is very limited. The only values I've seen besides OTHER are
- T-Mobile myTouch 3G
- Nexus one
- Droid
Everything else is related to OTHER. Obviously, the list of devices that he shares is very incomplete and not very useful. Until Google improves it, the Platforms sections are pretty much useless, and I recommend using a third-party library for more details.
