If I remember correctly vorbis does not have a constant bitrate option. The -b 
is probably used only for "hinting" at which bitrate you wish to have. It 
could very well be as Jan suggests, it will get higher after a while, or it's 
simply a bug. 
Anyway you are probably better of using the -q switch.

For your information. Testing done lately 
http://www.rjamorim.com/test/multiformat128/results.html
suggests that the alternative vorbis encoder 
http://www.geocities.jp/aoyoume/aotuv/ gives superior quality (to the 
standard encoder, and pretty much anything else).
