Probably. But it is perfectly logical if you think of "byte" as "smallest 
addressable unit of memory".

I'd agree with that, if "multiple" can mean "one or more".

Then they are using the term "byte" to mean something other than "smallest 
addressable unit of memory".

Like all disputes about terminology, this one will run for as long as we 
have the patience for it.
