Problem with PF_GetCurrentState() in Premiere Pro

I cannot make this work like in AE if I want to get the state of the current layer (index 0). I invoke it like 

A_Time curr_time = { host_time, ae_data.in_data->time_scale };
		A_Time one_frame_dur = { ae_data.in_data->time_step, ae_data.in_data->time_scale };
		suites.ParamUtilsSuite3()->PF_GetCurrentState(ae_data.in_data->effect_ref, 0, &curr_time, &one_frame_dur, &ae_state);

Returns different values on every frame. In PP however I always get the same state. Is it supposed to work in PP?
