Is it my imagination or is he dragging this right out?
Not your imagination. It's rather an illusion. This was done weeks/months ago and has been staggered out to retain the appearance of a channel creator hard at work. The "sushis" are just shorts created from the main video that are placed out there at intervals so it fills up the space and his subs get the notification that a new video is out every day. He'll also throw a random interview in there now and then to mix things up.
Think of it as like having a favourite television programme having 12 episode seasons with one episode coming out a month. In addition they release episode trailers, behinds the scenes content, and exclusive interviews with the actors a few times a week to keep you interested. So you are left with the appearance of non-stop programmes on television. Even Lloyd knows he can't go weeks without releasing new content. His patrons would flee in even greater numbers, so he needs to create this illusion of being hard at work and putting his donations to good use. It also serves to cover up periods of inactivity, such as the holiday he is on right now.
When he gets older, look for Lloyd Evans re-runs. He'll do a quick and updated intro to a video he did years ago.
