Im very sure even the same coffee species will taste differently if planted in different areas due to the weather, climate and soil conditions. So if same species, different origin, its definitely a blend. But thats me, not sure about anyone else.
Its pretty much the same with tobacco plants which are grown in different parts of the world using the same species but the nuances are worlds apart.

Interesting question to ask (though I'm still wondering why haha)
Single origin is typically referred to farm level. Thus the "origin" word is more location focused. So all beans from the same farm, regardless of varietal would still be considered SO
There's lots of farms that plant a mixture of varietals - Catuai, Caturra, Bourbon etc but process them all together in a single harvest and the beans are still sold as such
Of course those prized varietals like Panama Geishas are very meticulously separated and have a very focused varietal
Ethiopians however, due to economy challenges, sometimes don't market their coffee by farm level but rather by mill names, coop names or even just by region
These have even more "rojak" of beans from different varietals and farms packaged together into the same bag. Example : Ethiopian Sidamo Guji is basically from the Guji region of Sidamo province
Typically beans from Ethiopian are just recognized as Heirloom varietal as we know they are the "Originals" of coffee but could have hundreds of mutation within them
Just my 2 cents
