I may be able to offer an explanation .
I am an avid photographer and have seen similar effects before.
You can wager that any photographer using a DSLR camera , who knows his stuff , will have a UV filter permanently attached to the lens . This lens
filter can cause reflection problems when shooting at night . See Below.
Now it could be that the lights that have caused the similar reflection in the OP's post were out of shot , or conveniently cropped .
Please don't be swayed by the fact that the OP's pictures were taken by a pro , because he could be a wedding photographer for all we know , who is
obviously unfamiliar with taking night shots. Photography has many fields in which one could be considered a pro . It doesn't automatically make one
Just trying to keep it real . Any decent amateur or any pro photographer will back up my explanation
