So I messaged Daniel about this because I had installed them like the original pictures indicated (and how the stock ones were set up). Turns out I installed them incorrectly, so the pictures shown here and the DIY pdf are the correct orientation. Daniel said that as is I'm loosing performance, but it doesn't sound like it's causing any damage (phew). I'll be correcting mine ASAP.
