That was a good episode! The manipulation gag at the start was particularly amusing, although I do wonder why Rimmer would agree to do the cleaning. Then again he is quite a 'by the book' character at times and maybe he secretly likes it after his time doing the same thing as a Mechanoid. While I've thought they might be referencing the past a bit too much this series, I liked the way they did it here. It made sense, and it was funny. As for Rimmer dying twice, I saw this as a Timeslides reference as well. Okay, technically Rimmer only died once, just at different times depending on the time line. However, after the time line changed, Rimmer still retained his memory of the original time line, as he expressed surprise that he was no longer a hologram, so from his POV, he experiences both deaths. Maybe the others remembered the original time line too, or he just told them about it later. I'm not sure why they would remember. Maybe this is an earlier example of what Lister speaks about in his confusing monologue at the start of series 7, ie. a new universe being spawned to deal with the paradox with elements of both differing timelines. In the end, which was we're probably over thinking it though. It's just meant to be a gag.
