Is there any ordering rules on CAD command sequences in ABC dataset?

Hi and thank you for your great work!

I'm currently working on CAD-related tasks using the ABC dataset and am curious about the ambiguity of the CAD models in it.

A CAD model can be represented by multiple CAD command sequences
for example,

this model can be represented by

1. Make a big cube first -> subtract two cubes at each top corner
2. Make a bottom cube first -> add one smaller cube on top
   ...

So I'm wondering whether the CAD models' command sequences are sorted by any ordering rule in order to avoid ambiguity like this!

Thank you for your reading
