Valid is probably no good wording here.

I meant, if you pass an argument to `key-lookup' that is not defined
through KEYMAP, there is a well defined return value:  nil, or the
default binding respectively.

A key sequence that is "too long" is not valid as an argument in the
sense that neither nil nor a binding would not be a suitable return
value.

I think there is nothing said in this paragraph that you didn't
understand.  But I agree in that the explanation could be improved.

Michael.
