PHP background management, using aliases instead of the real login portal name, what is the purpose?

A financial background is written using the TP framework, the real login URL in its source code is admin/index/login, and the background home page is admin/index/index, but why it opens the route with an alias. For example:
safeadmin/ = > admin/index/login
safeadmin/index = > admin/index/index

is this done to keep outsiders from knowing [or guessing] its background URL?
