Right. Airlines who use married segment logic can (and do) treat married pairs as if they were completely separate bits of inventory.
I assume UA already knew the exact cause of the issue, but I really hope this doesn't trigger their engineers to go back and actually fix it.
For whatever reason, UA has been doing this frequently -- limiting the connecting inventory to a much more expensive bucket than the constituent nonstops.
