The initial code from earlier from today didn't really work reliable since it is not possible to apply virtual modifiers but not the real multires one (in a situation like mesh with shapekeys and multires). New code uses less memory and has better performance for the case when there are actual modifiers leading the multires. The case when there is only multires will not be as performant as possible at this moment.
