The key sentence is compatibility with Matlab.

Regarding inability to follow - the word "link(ed)" has different meanings
in the contexts of, say, symbolic links to a file <-> linking object files into
an executable.

I am unfamiliar with the "link(ed)" in the context of global <-> local variable
with the same name, and I gave the Perl example to explain the situation I'm
familiar with.

I do not have Matlab, and I do not have experience in it, that's why the concept
of linking global and local variable with the same name is unknown to me.
