A hard-link, or a soft-link? I am guessing the later, since you can't
hard-link a directory, but it isn't entirely clear.
If you mean "cloned by hard-linking all the files" then the answer is rather
different to what I am about to give you.[1]

It could be that you are seeing a cache effect, where the system has a copy of
the file in either an HTTP cache (if you are accessing this via the web) or a
local icon cache.

Assuming they are soft-linked directories, so the change actually happens to
the one single "real" directory, cache effects.

Maybe it needs more of a kick to do the right thing?

Given your description, it sounds suspiciously like HTTP caching, but it is
hard to be sure. Does the access log for Joomla show that the image in being
downloaded by the client, not just a "not modified" response?
Does Joomla maintain an internal cache of, say, rescaled images that might
need to be flushed?

Footnotes:
[1] Specifically, when you "delete" a file with hard links, you only remove
that one name associated with it. The other links are unaffected.
