[FFmpeg-user] -threads 1 seems not work

For a certain conversion I use '-threads 1'. As I understand it ffmpeg
should then only use one CPU. I see that the CPU usage is lower as
without this parameter, but it goes up to 180%. So clearly it is using
at least two CPU's.
Or am I understanding this parameter wrongly?

I am using ffmpeg version 4.3.4-0+deb11u1. (Debian always lags a
little bit behind to be more stable.)
