It's extremely easy for something like that to slip through. A typical 
editor would be looking for correct grammar and things like that and 
wouldn't necessarily understand the content even if they were paying 
attention to it, which they usually won't be.

That leaves the author to catch things like that. Unfortunately, the 
author knows what it is supposed to say and will often miss when it 
doesn't. Been there, done that. Have you ever written something (even a 
blog post) that you proofread a dozen times (and fixed errors every 
time), basically to the point where you were certain it was perfect? And 
then, several years later, did you go back and discover, to your horror, 
some glaringly obvious error? This is the same effect.

That said, sometimes deliberate errors are left in to trap plagiarism. 
That's probably not the case here, but it does happen. This is 
especially useful in cases where there are limited ways of expressing 
things correctly but unlimited ways of getting things wrong. Think fake 
towns or roads on maps for instance.
