Catch cans are absolutely not needed. The oil is sucked back into the engine because the intake runners, throttle body, valves, spark plug tips, and the tops of the pistons all need extra lubrication. Some oil even runs back down into the oil pan. It's the ultimate green energy concept of recycling
