I possibly misunderstood it, by I think that if I have some noncommercial or no-derivates license (such as CC-BY-NC-ND), then I am allowed to upload that source text to en.Wikisource.
No, you are not allowed to do that. The text under the edit box states "Please note that all contributions to Wikisource are considered to be released under the GNU Free Documentation License". CC-BY-NC-ND is not compatible with the GFDL, and is also not a free license, so wouldn't be acceptable on any Wikimedia project.
