Here are some scenarios:
If you both maintain course your paths cross and so depending on speed you collide.
If you turn to stbd you no longer cut his path (assuming you do so reasonably early and decisively -- but with radar thats possible).
If you turn to port you still cut his path, and so its all down to closing speeds.
If you do as suggested and turn to stbd and he also turns to stbd you will diverge unless you both left it way too late.
If you turn to port - then the other skipper may not be expecting that as its not the recommended practice in the col regs and so he turns to stbd as per the protocol and you end up still on collision course.
