It doesn't jump back to the first iteration, it just plays 50% of the 
third iteration. In effect it goes from iteration 0.5 to iteration 2.5. 
This difference is observable once you introduce accumulation behavior.

That's the correct behavior for forwards fill. There may be use cases 
which require other kinds of fill modes, however. If you have a 
particular example that can't be achieved with the existing fill modes 
that would be really helpful to know!
