I agree. It definitely doesn't hint at separation, which would have the tufts swirling, and ultimately flowing "backwards" up the glass at times.

One other thing I want to do is put tufts somewhere where I know the flow to be extremely good, like middle of the hood, and see how those look.
You can see what tufts in very clean flow look like in this video I did. Jump ahead to about the 2:40 mark - particularly note the tufts that are furthest forward and on the top row:

I was amazed that the turbulence did not get worse further back on the hatch. I had been conditioned to think that flow deteriorated as one got closer to the rear edge.
It does if the shape isn't optimal

All very interesting. Seems Honda got it pretty much right.
Seems that way.
