I thought the spec was quite clear:

(a) If there are more numbers than format tokens, then the last format token
will be used to format remaining numbers

(b) Each number after the first will be separated from the preceding number
by the separator token preceding the format token used to format that number

So if there is one format token, then it is used to format all the numbers,
and each one is separated from the preceding number by the separator token
that precedes that format token.

(In reading the XSLT 1.0 spec it helps to know that it was written by James
Clark; I asked him many questions similar to yours, and would always get
replies that suggested I should take the text as written at face value. He
never wasted words, and the text invariably means what it says, even when
you think it might not. The fact that the same phrase is used in the two
sentences above "the token.. used to format [the number]" is pretty clear
evidence of the intention.)
