What is to stop the union charging session fees for each occurrence of an ad that has many versions and hence many Ad-IDs?

There are acceptable edits, lifts, and tags that are considered "derivatives" of the original spot, and allowed within the original commercial. You should get to know these rules, and use the Ad-ID derivative function. The number of Ad-ID's has no relevance to the number of commercials produced under the commercials contract any more than changing ISCI or other identifiers were in the past.
