To reproduce
(using GM 3.5beta4 stable in Nightly 44 x64)
(it doesn't occur in GM 3.5 stable in Firefox 41.0.2 stable) :
create an empty userscript, e.g. test, containing just this line:
// @require http://code.jquery.com/jquery-1.11.3.min.js
and reload the page.
You'll see in gm_scripts\test that the jquery-1.11.3.min.js is downloaded
Now edit that line into
// @require http://code.jquery.com/jquery-2.1.4.min.js
and reload the page.
You'll see now that the new file is not downloaded (the previous, query-1.11.3.min.js remains).
