Not sure - I don't have any.

The same reason. The part is effectively a torque limiter - it even has the
nominal torque limit printed on it (2.5-5.0 Ncm) - where it is placed in the
gear chain simply decides how much maximum torque is available at the output.
Lowering the gear ratio after the limiter increases the output torque available,
raing the ratio decreases the torque limit. So putting it before a 1:24 gear
reduction increases the torque available by about 24x.
Hope this helps.
