To me it just seems whoever wrote this has no idea how it works, and whoever reviewed it and approved it to be published is equally incompetent unless it was intended to be deliberately deceptive.
But if you had a journey that had multiple legs, e.g. MAN-LHR-JFK, if you upgrade the transatlatic you still get two bags on the domestic.
I think this is what they mean. A single journey (with no stopovers) could have several legs in it, and (as you elude) your hold luggage allowance is determined by the main segment, you don't get it thrown out halfway. Just because OP is travelling direct does not mean this is what happens for every journey. The text is not written to apply to the specific scenario that is being booked, but is generic for any upgrade.
