HVAC airflow is opposite on Auto

I've used the Auto setting on BMWs since e39 in '96, and loved it. On my '10 e92, I noticed that when car is:
  • heating interior in winter, some warm air blows to windshield, and not much warm blows to face or feet.
  • cooling interior in summer, cold air blow to feet. And this is a significant amount of cold air.
  • Instead of Auto and 72, I have to manually select face and feet in winter, and face and windshield in summer, which reminds me of e30 dials only I can't specify the split volumes.
Anybody else experienced a similar problem or a solution? I'm taking car to dealer this week so any advice would be appreciated. When I've mentioned it before to dealer, they said this is normal.

It starts off on windshield, since this is required to defrost. As the cabin warms up, it redirects to feet, and once the air is warm enough, it enables the face position. Same as my E46, haven't noticed any difference.

Slow airflow when cold. Once it warms up, yes, increased airflow to defrost. But airflow doens't stop there, airflow continues to increase to defrost, and stays there. Minimal airflow to face, and none to feet (I checked).
