Which implies you meant that the chain line, chain stay clearance etc were exactly the same, since as you put it we don’t measure BB’s from the centre out the difference between the two tapers is half the total difference between the two lengths I.e. (111-107)/2=2

But the overall difference is 4-5mm. Thats why I reinstalled it in the Royal H with a 111 ISO BB. If I thought that the change would have been 4-5mm per side I would have installed it with a BB in the 120ish range.
