I think you misunderstand the English word nonsensical.  A
statement can be unlikely, silly, or ridiculous, but none
of those make it nonsensical.  In fact to say a statement
is unlikely more or less automatically implies it is sensical.

I mean I find the statement consistent with what the standard
does say.

Despite what Wikipedia may say, that's isn't what the word means.
I recommend, especially for people for whom English is not their
first language, consulting a dictionary (or better, more than one)
whenever there is any question about what a word means or whether
a particular word is a good choice in a particular situation.  I
routinely consult dictionaries when questions like this come up
(yes, even though English is my first language).
