I am afraid that I don't know Druid enough to understand what does the above reindexing actually do with the sketches. Are they downsized in the process? Are the dimensional combinations altered in some way? Theta sketch algorithm is deterministic in a sense that merging the same sketches in different order still should produce exactly the same result.
