I do remember that statement being made towards the end (by Morris?), but I don't see how it leads to anything bigger or nefarious. He's simply saying that if you built a point in your talk around a verse that uses word X, and now the verse uses word Y, you need to find that problem before you give your talk. It would be remiss of him not to give that reminder. I'm not discounting the possibility that changes in the new Bible might have been made to support doctrines or doctrinal changes, but until we have evidence of such, this is taking a bit too far of a leap in thinking.
Splash: The GB speakers multiple times actually referred to "the Governing Body" in the third person, not just the F&DS (and yes, we know they're the same entity now). But as stated above, since they're a part of the whole, this isn't totally unwarranted or strange. A CEO will often refer to his company as something that does or that, rather than saying "we". It's an ordinary mode of speech. I do think that, in the GB's case, it's a feigned humility, though.
