meetBDVState looks pretty difficult to read and follow.
This is purely NFC but doing several things:

1. Combine meet and meetBDVState
2. move the function under member of BDVState
3. Make BDVState be a mutable object.
4. Convert switch to sequence of ifs
5. Adds comments.

The patch is published to get a feedback whether this change simplifies the reading of the method.
If it is not, I'm fine to abandon it.
