The reason for particle superposition is actually an illusion . Both the the queries you raised were in fact correct. Particles appear to be in 2 places at the same time because we are viewing them from a much different time layer. Particle data at its source is just a discreet wave patterns that can be copied and repeated. 2 matching wave frequencies are seen to be effecting each other at 2 places in a way they appear to be breaking the speed of light. That is because the measuring stick we are using for "light speed" is in our time layer. If we were to shrink down to a particles time layer we would notice the identical wave patterns do take time to propagate at what ever clock rate or "light speed" that layer has. This gets further complicated by the fact that if needed data can move between time CTC levels for many reasons. This is why during high speed collision of particles "virtual" particles appear to pop in and out of existence as error correcting algorithms run to re-stabilize the system effected.
