I don't think the following information is actually documented somewhere, but I want share the discovery I made by making some tests in the URL for trying solve your "problem".

Saying this, you can remove your "problem" - (which is: displaying the same video twice) - by modifying the URL as follows:

https://www.youtube.com/embed/VIDEO_ID_1/?playlist=VIDEO_ID_2&autoplay=1&loop=1&rel=0&showinfo=0&color=white

Explanation:

• VIDEO_ID_1: Corresponds to the videoId intended to play continuously - (in loop).
• VIDEO_ID_2: Corresponds to the videoId usted in the VIDEO_ID_1, BUT with the last letter changed. The idea is set a videoId that does not exist.

So, with the previous explanation, you can use the following video as an example:

Video: Stack Overflow is 10!

videoId: QwS1r1mc888

The modified URL shows the following:

https://www.youtube.com/embed/QwS1r1mc888?enablejsapi=1&loop=1&playlist=QwS1r1mc880&autoplay=1&rel=0&showinfo=0&color=white

N.B that the videoId QwS1r1mc880 does not exist (yet) - you could also replace this value for 15874598752 - which will never be a YouTube videoId (as far as I know).

Side note: I really hope this discovery won't be removed.
