Very good point.
I've never heard this particular example, but I can see it would cause confusion. "G-XX climbing to two thousand feet" (or is that "climbing two two thousand feet"?) is another. I'm sure there are many others.
People in general, and pilots in particular, don't seem to like following instructions to the letter, and often with good reason. But CAP413, with the exception of position reporting, is a very thoroughly thought-out document. Stick to what it says, and you won't go wrong!
(Out of interest, how many PPRuNers regularly use the word "niner" on the R/T?)
