A dot is missing.
That's because the two dots are of the two aes2. are joined into one
single dot. Which is hidden by \hideNotes.
holy moly, this way of notating is so wrong I had no idea what was actually going on. So, what's happening here is that the aes and the ees both start on the first beat? They're simultaneous, but offset horizontally and with their stems pointing opposite from normal?
Yeesh, that is terrible.This is why it's important to follow good notation practice: I was so confused by this bad typesetting that I thought the bar was 6/4 time, and now my day is ruined.
