As a pre-emptive rebuttal to any apologist who may say we're reading too much into the WT's elder training videos, and the details we've pointed out are benign, here's WT's bold claim:
"...In summary, the Writing Department insists on using only material that is accurate and truthful, even regarding seemingly insignificant details. As a result, “the faithful and discreet slave” can consistently supply spiritual food that brings honor to “the God of truth,” Jehovah."
2011 Yearbook, page 9.

w87 3/1 15 'Upon the Watchtower I Am Standing'
"Each article in both The Watchtower and Awake! and every page, including the artwork, is scrutinized by selected members of the Governing Body before it is printed. Furthermore, those who assist in writing articles for The Watchtower are Christian elders who appreciate the seriousness of their assignment. (Compare 2 Chronicles 19:7.) They spend many hours in researching the Bible and other reference material to make sure that what is written is the truth and that it faithfully follows the Scriptures. (Ecclesiastes 12:9, 10; 2 Timothy 1:13) It is not unusual for one magazine article—that you may read in 15 minutes—to take from two weeks to over a month to prepare".

This was printed prior to WT's extensive use of video and, obviously, the Internet or JW.org. But, they've printed nothing since that time which contradicts the above quotes, so we can reasonably conclude that everything in the videos, even "seemingly insignificant details", are there intentionally.
