Vintage is just a nice word for outdated.
If you want to advance a hypothesis you need to use more precise language. I don't think anyone ever marketed a "normal" bike. What are you talking about?
FWIW, these are 28x2.0 tires. I don't think anyone would confuse them with 29r mtb design
Equally, early era MTB/ATB's could not be confused in any way with modern "hybrid design. This is a 1984 Norco that shows such initial geometry (the first commercial MTB was in 82). Yes, it's got mis-matchy parts, I just picked it up off CL.
