Not really - the 412 system is pretty crude (I am guessing) as it doesn't have a concept of final approach track, it just makes a heading changes in response to localiser deviation and rate of deviation change. I have never flown one but I would suspect that if there was a big change of wind near the bottom of the ILS, or turbulence, or pilot selected change of airspeed, that it would not work very well - at least it could be exploring the limits of the ILS needles! That is how the 4-axis AS332L autopilot behaves anyway, and the L2 is not that much better.
With the modern autopilot, even when the crosswind component near the bottom changes substantially, there is no localiser deviation as the system is maintaining the final approach track by changing the heading before a loc deviation occurs.
