If you get a backlink, probably your document will be correctly seen as the cluster representative. Sometimes it can happen that your content is filtered (but there is no duplicate penalty) because the syndicating site is more authoritative than yours, or if your indexation frequency is lower than its and so the syndicate content is indexed before the original one.
If they use the unedited feed, however, you can get some deeplinks if you have internal linking in your contents.
