Here it says that bitrate mode is variable

My question is, I convert just the audio and leave the video are "copy source". The resultant file doesnot mention variable bitrate, so, did I lose the variable mode to constant mode? Is there any way to retain variable bitrate mode? If the question appears noobish, please don't be sarcastic....
Thanks in advance
