Does the rest of the article seem to resemble a state machine to you, or do you see an obvious way that the classes he wrote could be used to create a state machine? Because I do not.

Hi,
The main peculiarity about this solution is that on this case we had a complex input type, where a transition on an inner element may influence the state on the outer element.
For example, given the following structure:
- A1 (state=1)
-- B1 (state=2)
--- C1 (state=5)
-- B2 (state=3)
If the state of C1 changes, then this change should be considered by the B predicates, and so should the A predicates.
After all, for the example in specific we are returning all the updated statuses in a list, as in our case we needed to show what was the difference on the overall state after the execution.

Nice article!
After deeper thoughts i finally realized what bothers me about it: It doesn´t address the inner dependencies between those transitions.
By your comment above, it´s not a big deal because of this kind of hierarchical structure you described, but it was not clear when i first read it.
