It's a tutorial, which is giving some hints on how to use "p0". The case is rather fast to run, so the idea is that the value "p0" is set to 40 because continuing the case will probably be after 1.0 s or 1.5s, at which point in time, it's already at 40, as indicated by the time table. In other words, it's so quick to run, that it's more likely to stop after 1.0 s, than anything else. Have a look at the "controlDict" to see what I mean.
