I can confirm this issue in Safari 9.1.1. However, the important keyword here is "flash" - it doesn't affect the HTML5 player, only the legacy Flash player. In order to get the Flash player I had to change Safari's user agent:

defaults write com.apple.Safari CustomUserAgent "\"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9) AppleWebKit/537.71 (KHTML, like Gecko) Version/7.0 Safari/537.71\""

This will cause YouTube to show the Flash video player and it will play an advertisement for these videos. Adblock Plus 1.11 is fine, only Adblock Plus 1.12 shows this behavior.
