Instantception: Repeat for each instance

Just to see if sub-events worked as expected and if you could have repeat for each instance within a repeat for each instance within a repeat for each instance, I created the following scenario.

We have 3 groups.

Objects (or Tools or O) - There are 3 instances of them.
People (or Humans or P) - There are 2 instances of them.
Animals (or Pets or A) - There are 4 instances of them.

Per this code, when we hit space the following happens. I am neating it so, we can see it better.

O1, P1 - A1, A2, A3, A4
O1, P2 - A5, A6, A7, A8

O2, P3 - A9, A10, A11, A12
O2, P4 - A13, A14, A15, A16

O3, P5 - A17, A18, A19, A20
O3, P6 - A21, A22, A23, A24

Looking at this, basically, the way the repeats execute seem logical.

It starts with Object (top-most) and then goes inward to Pet (middle) and then to Animals (bottom-most) - resolves all of Animals as it is the inner most and then goes back up one level to Pet (which has sub-set of animal again).

So essentially we are expecting.

Object to execute 3 times.
People to execute 3x2 = 6 times.
Animal to execute 3x2x4 = 24 times.

To be correct, you should really reset the variables Hum and Pet before their repeat loops. Then lines will read:

O1, P1 - A1, A2, A3, A4
O1, P2 - A1, A2, A3, A4

O2, P1 - A1, A2, A3, A4
O2, P2 - A1, A2, A3, A4

O3, P1 - A1, A2, A3, A4
O3, P2 - A1, A2, A3, A4

because there is no P3, P4, P5 or P6, and similarly A5-A24.

That is correct. Your way would illustrate that better.

I was just trying to see how many times does each repeat play and also the sequence of their execution.
