This is related to changes that we made to the bootstrap namespace in Mac OS X 10.6.  Specifically, we flattened all of the bootstrap namespaces for a given user.  The best way to think about this is to look at Figure 3 of TN2083 [1].  In that diagram, each pink box has been merged into its parent blue box.  This means that there's only one bootstrap namespace for user, so it now makes sense to map from a user ID to a bootstrap namespace.

While this is clearly a bug in the technote, one important mitigating factor is that, if you follow the design advice from TN2083, everything will work on 10.5 and 10.6 (and probably future systems).  One day I'll get around to update TN2083 for 10.6, but today is not that day.
