Pretty much yes.   They take the page they land at and search for the
URL header in the infobox table, then take the first URL that they
find there.   In the example case this means following the Wikipedia
redirect from https://en.wikipedia.org/wiki/scihub to the official
page https://en.wikipedia.org/wiki/Sci-Hub, where the Taiwanese site
is the first one, of four, listed in the infobox.

Kind of an odd thing overall.  I'm not sure what real utility it has,
and so I'm having a hard time imagining wanting to use it myself.  If
I really wanted to go to a URL via it's Wikipedia page, well I already
have a Wikipedia keyword search in my browser to get me there quickly
enough, just one extra click overall.
