This is a common misconception Remember this is a wiki and sentences may be moved added to and so on Just few days ago I reviewed a DYK and asked the nom for an ref for the hook inside a para The para first and last sentence had the same ref and you d think the middle where the hook was from would have the same one right But it was instead another source the nom used but forgot to add to that para This is just one of many cases which prove that it is better safe than sorry and referencing each sentence is the right thing to do For UZZ imagine what if somebody were to add new content to the middle of that para with a reference would you then assume that the beginning of that para is referenced with the new middle of the para ref Or split it into two thus leaving the first one unreferenced I hope you see now why each sentence has to have its own reference Could you restore the refs you removed Thank you
