Sorry, but me thinks that is stretching it quite a bit.
I will challenge you on the Catskill method. I will match you 10-1 with photos of upright v. Slanted. In fact, let's produce tying instructions for Catskill to see what the drawings/instructions say.
Regarding the comparadun style, all who tie and fish them will tell you there is a nasty little tendency of forward creep in the "wing".
Just one example here. The cover of Eric Leiser's great book "The Dettes - A Catskill Legend"
Note the dry flies on the cover. I could also post a picture of their instructions on tying the wings upright if you like.
And, casting these flies does not make those upright wings cant either forward or backward once they alight on the water.
Now, what would be hard to refute is this. If a Catskill dry fly does indeed stay afloat on its "float line", there IS a bit of a canting of the fly upward at the front end of the fly....................
Here is a Theodore Gordon tied fly in Fly Fisherman Magazine:
