Yes it does! Look at the formal syntax definition for those numbers. You 
will see that they ultimately resolve to either of these:

number          = 1*DIGIT
                   ; Unsigned 32-bit integer
                   ; (0 <= n < 4,294,967,296)
nz-number       = digit-nz *DIGIT
                   ; Non-zero unsigned 32-bit integer
                   ; (0 < n < 4,294,967,296)
I think that is pretty clear! One could argue the textual description of 
the protocol could make that clear, but the formal syntax is always where 
you should look when the text is not clear.
