Not necessarily. FWIW, every S&P department is a little different. Some will react the way you're describing, as in, "isn't it a little disingenuous to say [this bit of host language]" and try to suggest alternate phrases to use on the air and/or new rules. Other departments will work in concert with the producers to make the rules fit the host language.
The target number is randomly generated, which Geoff reminded the audience of every time in the extant '70s episode. That felt deliberate...as in, it explains why you might never hit the target in a game: it's completely random. So long as you avoid saying things that are demonstrably untrue -- like "every game, we guarantee every target number can be hit" -- you're fine.
As one S&P rep put it to me, their job a lot of times is to make sure a show adheres to its own rules (once they're set).
