Yes. Ok, well, MeshFunction itself doesn't care (as you found out)... but if you want to evaluate your solution in elements containing off-processor degrees of freedom then you need to serialize that vector.
Think of it this way: MeshFunction doesn't do parallel communication... you are responsible for feeding it the values you need.
