That's how it used to work, but not anymore. Album length is now the determining factor. I think albums over 100 minutes long get counted twice, but anything below that won't be, no matter the amount of CDs it has. That's why TBOS was not double-counted - whatever the number it's reported as selling is the actual number of units moved (or shipped to retailers, as the case tends to be). I don't know how the counting works beyond that (logically you'd assume it goes up in 50 minute increments since that seems to be the "standard" length of an album under this definition) but it's kind of irrelevant anyway, since Bruce most definitely did not sell 20k copies of his boxset, let alone 200k.
