AC3 audio codec transformed into vorbis after conversion

Hello.
By retaining the AC3 audio input codec, this is transformed into a vorbis output. Is this normal?

Conversely, I also think that ffshare cannot convert the vorbis format into another audio format (for example aac) when the audio input format is vorbis.
