New flat winding system of C600

Why can C600 wind the line flat ?
Shimano's low priced models is same system .
I don't know who is first .

Oscillating system of C600
Its pin has 2 diameter . The cum is same .

Ordinally system
The speed of spool is reduced in near point of edges . So, it cannot wind flat .

C600
The larger diameter of pin works from red to yellow . The smaller diameter of pin works from yellow to green .

The speed is not reduced on the edge .
