Yeah - it seems like this will cause a series of 5 second skippable ads that still sums up to >many seconds of unskippable ads (unless that's banned, in which case they will just see ads more often, as you say)
I expect it will make the experience worse rather than better because the publishers will try to maintain their inventory (how many seconds of ads they show per minute watched)
