How does ANGLE_MAX affect autotune?

Hi all,
I recently came across the ANGLE_MAX value which seems to be exactly what I was looking for as I have a well powered copter and need to reduce fast flight actions.
The documentation says that ANGLE_MAX is the maximum lean angle in all flight modes. So I assume it works on roll and pitch and also in AltHold and Loiter. However, what happens while autotuning? Will the copter ignore that value or will it also reduce the lean angle while tuning?
