Yes. But invoking a command is not being a command.

Presumably you mean that using key sequence `C-x &' is equivalent to using `M-x 
universal-async-argument'. That's another way of saying that `C-x &' invokes 
command `universal-async-argument'.

If you wanted to call command `universal-async-argument' a "prefix command" you 
could do so. But `C-x &' is not a prefix command or any other kind of command.

Command `universal-async-argument', when invoked, precedes invocation of the 
command bound to the key sequence read by `universal-asyn-argument'. Yes.

And using `C-x &' precedes reading of that second key sequence. But neither of 
those things make `C-x &' into a command, prefix, postfix, or *fix.
