JM,
You are slightly incorret in your definition of version 1 and version 2 plays. Version 1 - all opposing teams must be from opposite conference. Version 2 - two of the three must be from opposing conference, but there is no requirement as to the order of play (same conference team can be the first in the series, the middle or the last). All of your other points are valid.
