I'm not sure why our moderator @davidpostill reopened this.

Neither question was a good fit for this site. No one, unless they work for your ISP is going to know why they choose to route this way. (other than contracts or design) It's why the ISP on network diagrams is a cloud. No one knows how the ISP inter-switched network operates from A <---> B, it's company specific & private. It may change packet to packet based off of the individual routers decisions from interface/link load ect. Even if someone here did or does work for them, discussing the inter-switched carrier grade networks of ISP's would be off-topic per our help section guidelines. ~(personal & home networking). 

"While on the same topic, the questions are unrelated.

Now the new question got marked as a duplicate. The edited question is still closed as not focused. Does that seem right to you?" 

~ Yes, either you are disingenuous with your petition, or you really didn't understand what I was trying to tell you in the comments.
The two questions were most certainly related.

I really doubt anyone is going to attempt to answer it, if they do it will be a generic meaningless answer that will have nothing to do with your ISP,  not help you solve anything, and will not help future readers.

For these reasons, I am petitioning the rest of the community moderators to vote and close this question. https://superuser.com/questions/1553653/why-is-this-international-internet-traffic-routed-so-inefficiently
