Steel Twister Shuttle

Can anyone explain to me why if you make a steel twister coaster that has a launched lift hill goes on top of some high land, does some sort of inversion (for example a large loop) then goes up higher than the loop so that way the train cannot complete the inversion and has to go back through the loop, the test results come up so funny. I did this without a trainer and comes out pretty well. It's sort of cool but I don't understand why it works.

For example, I added one loop and one top-hat (the top hat was to make it so the train couldn't make it over the top) and then it went backwards into the station and said that it had done SIX inversions. In my book that's not six.

If you're going to try shuttles with the steel twister, just to full-circuits. if you only have 1 train, you can set it to more than 1 ride.

for example: station, launched lift, boomerang, vertical loop, another boomerang, and walla.
