Help - check me out, as my understanding of this is not quite correct.

For the Short Program, the Worlds Standing selects the skaters to be put into an individual Group.

Then each group draws straws for selecting the skating order for that group, and only that group.

For the Long Program, the Results of the SP determine the skaters for individual groups.

Then each group draws straws for selecting the skating order for that group

I used to think the ISU would have the skaters line up for the SP according to exact World Standings with the skaters skating in positions from the lowest to the highest standings.

The LP would show the reverse order of the results of the SP.

That doesn't seem to happen. What do I need to know?
