If you are asking if the inline citation should re-state what's in the "Sources" section, I don't think that is necessary. If you're asking if the two should dovetail together, I do prefer that they do.
I like to use the <ref> and </ref> tags so that the inline citations in the profile show up in the Source section--with the net effect that at a glance, a reader of the profile can tell that there is a specific source for the statement just made. I don't usually have much of anything fancy in the inline citations--they are just numbers referencing down to the numbers in the "Source" section at the bottom of the profile--but using the <ref> tags this way seems wonderfully specific and thorough to me, so I like it.
Admittedly, use of the <ref> tags for inline citations can be challenging for people not yet familar with html coding--though it seems to me to be fairly straightforward to learn.
