That is not a dependency, it's an incompatibility. The mod was renamed once, and that's just the old name of the mod. It's just there to prevent the same mod from being active twice.
I also renamed my mod once, but i just renamed the display name that is shown on the mod portal and ingame, not the actual name of the mod. Is there a reason why you renamed the actual mod name too?
Personal preferences and easier automation. I renamed the really old mods so all of them are now "eradicators-something". Also I dislike modname <-> filename mismatches, so I took the chance to fix that when it came.
