Do these variations only appear on the website version of YouTube? I use an ad-blocker so I haven't noticed this pattern exactly. However, one pattern I've noticed using the mobile app is that in order to disrupt the automatic habit to skip, they seem to randomise whether or not they make any specific ad skippable. It seems some ads are always skippable, some are sometimes skippable and sometimes not and some are never skippable. It doesn't always correlate to how long the ad is either. Overall this seems to result in my actually watching the ad all the way through because it takes too much effort to figure out what kind of ad it is and whether I can press the button at the right time. At least if I do nothing, I know the video I want will play eventually.
