I can't explain why off hand, but I can tell you that you're right. Bipolar parallel will give much better high speed torque, and sometimes a little less low speed torque, than Bipolar parallel. I believe it has to do with the inductance. RUnning you're motors bipolar parallel gives you a wider operating speed range, as bipolar series wired motors have torque curves that drop very fast.
