I don't think that I'm making my thoughts clear, sorry. I was thinking of someone in Seattle for instance who has to fly to India. They can choose to fly LH or UA via Germany; or they can go the other direction via Asia on UA and another *A carrier (or another carrier altogether)

Again the arrival and destination combinations are relatively low where this policy change may have an impact, but if it drives someone away from LH TATL onto a non-UA carrier TPAC then the carriers within that group do lose the revenue. SEA/PDX/YVR to India is probably the most likely situation for this to occur. It may especially be true considering how particular the agents can be at the Indian LH counters. I know that if I do use my 'blank' certs from India I can expect at least some push back, based on past experiences using them under the old process.
