only once

Tested on 2015.11.10 with the same result

This is expected behavior since by default youtube-dl prefers DASH bestvideo+bestaudio over best when no format selection is explicitly defined and ffmpeg/avconv is installed. So the first URL is for bestvideo and the second is for bestaudio correspondingly. If you want single file media to be preferred use -f best however you'll get worse quality in most cases since usually best qualitiy is served only via DASH formats.

Thank you dstftw, '-f best' does exactly what I need.
