Youtube-dl doesn't always download the currently playing video when specified "--no-playlist --max-downloads 1"

[chaochichen]

Trying to download the playing video at https://www.youtube.com/user/coolschool?v=DiJkxmKGRpk with "--no-playlist --max-downloads 1" command line options, the youtube-dl downloads the first video from the "Uploads" playlist instead of the one that is currently playing on the web browser screen with the same URL link.

Based on the "youtube-dl --help" screen:
--no-playlist download only the currently playing video

So, this is an obvious defect in the youtube-dl for the Youtube.com site.

youtube-dl.exe --verbose --no-playlist --max-downloads 1 https://www.youtube.com/user/coolschool?v=DiJkxmKGRpk
