It should be working, it allows multiple positions to be opened at the same time. It can be best perceived on market strategies.
If you have some strategy that behaves strangely, please attach it and I will take a look at it.

I modified its parameters (shown in a screenshot params_edit.png) and started retest. Then in a resulting tradelist I can see that multiple positions were open at the same time (screenshot tradelist.png).
Please try to modify the parameters as I did and retest the strategy. Then you shouls see that the strategy behaves as expected.
If you still have some problems, let me know.
On your suggestion, the duplicate trades option will be stated in Pseudo code to make it easier.
