I don't really understand that

Could you please explain that in a few more words in case Himeno does not?
Another question, regarding changes in the routing:
"Changes other than to Date/time/oneworld carrier/inventory permitted at a charge of USD125.00 per transaction."
What is a transaction? Do they charge only 125 USD even when I change multiple flights of my itineray at once or do they charge 125USD for every flight segment which differs then from the original itineray?
