Let me think about this some more. I'm not sure if 'Arrow Shaped' is another name for 'Set-Oliver'. Maybe it is. Maybe it doesn't apply to all plants on that page.
I used to have 'Set-Oliver', or at least a plant with that label matching the descriptions I've read. It was different in a few ways from the hairy plant I have been calling 'Arrow Shaped' (which was a random gift cutting from the neighbor). It had thinner leaves, thicker and more naked stems, fewer branches, redder flowers. So maybe there is more than one hybrid in the vicinity, but I agree the stemminess is not a setosa trait. And I also see different plants here (ie. these are not the same cultivar, if I had to guess)
The flowers on my plant are two-toned (orangey red/yellow), sideways at anthesis, and relatively crowded at the end of inflorescences. I need to take a better close up picture to document what my brain foggily recalls.
I guess the most conservative course would be to move the images in question to the genus entry if you don't think any of them are setosa, because I'm not confident they all correspond to 'Set-Oliver', or are all the same plant. I'm also having trouble finding the name 'Arrow Shaped' in any reputable source for names in this genus.
