The above reads wrong to me. The expression has to be read differently depending on the tinny detail that is the sign of the step that comes last:

* positive step: from 0 to 9 striding by 2
* negative step: to 0 from 9 striding by -2

Am I the only one thinking it's a bit too clever to swap the start and stop parts like this?
