I noticed that, too. It's a good catch. I think he was trying to walk the same fine line the WTS does, where they want people to feel as if the end is imminent, but they do not want to commit to anything too specific, lest people lose patience. He wants people to feel as if they have to support him, or he will stop making videos. But he also wants to appear as a strong and determined individual who will overcome adversity.
But he doesn't know how to express himself very well, especially when he's manipulating people. It's how he has treated his wife, as well. He's neither as erudite nor as clever as he believes himself to be.
