The basic idea is that any extra fumes vented from either the engine or fuel tank go through the carbon, to filter the air when the engine is not running.
On US B210s, Yes it goes to the fuel tank vapor return line (actually teed into it in the engine compartment with a valve). The 1200s (no cannister) have a three-way valve on the firewall, one goes the fuel vapor return line, another to the crankcase and the third to the air cleaner (B110). In other words when the engine is off the vapors are (theoretically) 'trapped' in the engine crankcase vicinity. But when the engine is running, the fumes are drawn into the air cleaner (carb).
The carbon cannister is a much better idea ecology-wise and doesn't hurt performance either.
