Right. Xvid first pass does a constant quant encode with quantizer 2
(lower == higher quality). Second pass by default wont use lower
than 2 either, so if first pass was already too small, then second pass
wont get bigger either.

Try adding these for second pass:
min_iquant=1:min_pquant=1:min_bquant=1

Some people say that encoding at quant 1 is overkill, but if you want
to burn some bitrate, those might help...
