Question on a graph

I was looking at this graph here

(which I finally think I understand now, thanks) and I have a question. It seems that the results for 1st pick only and 1st and 2nd are identical, which strikes me as very unlikely. Is that an error? In my own case, I believe I got fro 3 votes if only the 1st are counted, but 12 when you count the 2nd too (according to another editor's analysis), yet my bar on the graph remains unchanged. Or I could easily be missing something or misunderstanding the graph entirely still (far from impossible). Thanks.

You are absolutely right - this is a wrong version. I uploads the correct one. For the record, here the numbers I have used:
