Doesn't the WT claim that all content is vetted by at least three GB members before going to print?
Obviously, three copy editors with a high school education can't quite get the job done. Thus the continuous avalanche of flip flops, contradictions, and outright lies slip through the cracks and into print, year after year.
There is ZERO quality control at Watchtower headquarters. That is why if you are trying to get an active JW out of the cult, it is always best to use their own words without any outside information. That is what got me out.
