Mirroring is done for each variant and each platform, but not every 
combination of variants or of variants and platforms, due to the 
combinatorial explosion that would entail. Only the files needed by 
+universal on the machine doing the mirroring are mirrored.

In this case, the files are (on i386) also used for reasons other than the variant being set, so end users don't have to actually use the variant to benefit from its files being mirrored.
