Exactly. It works like PATH, LIBRARY_PATH, LD_LIBRARY_PATH &c. (Using
relative paths for require is, therefore, not recommended.)

If you mean that it doesn't encourage hierarchical module directories,
then, no, it doesn't. Something "required" is at the level of a
library, not of a module.
If you want to think of your requires as modules, you can use the same
solution as Perl, which is to
require "lib/submodule"
which makes your intent much more obvious than using relative paths.
(Which languages do use relative paths for this? Java doesn't, Perl
doesn't, C doesn't, Python doesn't...)
