Confused on paralleling BenBoost.

[die4laser]

So I try to parallel two BenBoost (900mA each) to get total 1800mA for my M140. However by looking at the schematic if I do this the two ben boost is actually have their senses resistor paralleled. In this case the resistance should be cut by half. Just wonder why two drivers will not affect each other if I actually parallel them?

That's the point of putting them in parallel. Calculate current using the new parallel resistance value. It will be the same as adding the original currents together.
