It's just a different skill. It's a skill that correlates with one another, it's a skill that if you develop on one side you'll also be getting better at the other.
It's the same physics engine. Multiplayer is about addressing problems caused by the opponent while simultaneously creating problems for them. You only get 20 seconds to do that and any major misplay is the difference between lifting your opponent and being lifted out yourself.
Single player is usually about creating something pleasing to the eye. Sometimes you also aim to do more quantifiable things like break speed or DM records as well. You have the luxury of taking as much time, tries, retries, edits etc. down to the single frame by frame.
Yes "entry level" wise, multiplayer's skill floor is lower than single player. Mostly because if you don't know how to play Toribash, you're not going to do anything like Boom Hit Uke, but you could find out how to not fall in judofrac meanwhile your opponent double contacted his knees to essentially fling himself into DQ. Reaching the highest level of either SP or MP is insanely hard to do
There are very few amazing single player replay makers. Proportionately, if you're a single player replay maker, you have a higher likelihood at being really solid at it whereas in multiplayer the majority of players won't be extremely competitive. At the end of the day there are only a very small set of players who have reached an insanely high level of play across many mods.
This is apples and oranges though. We don't need to say "but this guy is one of the best lenshu players in Toribash and he admitted he can't do SP" or "This guy makes insane replays but is just dreadful in MP" just for the sake of it. People will end up working on what they find more enjoyable to do.
