Why 2 different phase wire are not supposed to pass through same conduit?

According to the wording ,2 different phase wires "can" run through the same conduit. Not only can they, but if they are part of the same circuit they must. And in cases where conductors are paralleled, meaning more than one conductor per phase as is common in commercial and industrial installations, you put one conductor of each phase and a neutral, if one exists, and a ground in each conduit. Not doing so, meaning to put all of one phase in one conduit, causes a voltage to be induced into the conduit and a tremendous amount of heat builds up. Even when using pvc or other non-metallic conduit, somewhere along the way you have something metallic and have the same problem. To simplify, you must put all conductors associated with the same circuit in the same conduit.

Can you use PVC electrical conduit in a commericial building?

I know of no restrictions on using PVC conduit in commercial buildings. If it is subject to damage, meaning if it is exposed to moving machinery, forklifts, people, etc., you must use schedule 80 PVC. "Normal" PVC is schedule 40. PVC is easy to shatter, which would expose people to danger. EMT or rigid conduit would withstand damage much easier and wouldn't shatter in whatever event may happen. PVC is extremely difficult to customize to make it go where you want it to go and at the same time make it look nice. This in itself may be a code violation as the code requires electrical installations to be done in a "neat and workman-like manner."
