results of track-dynamic-topics.py

In the results of track-dynamic-topics.py, as shown in - Dynamic Topic: D01, there are 3 topics in window 3.
I am confused. The result means we got 3 topics in a time window?
how to get the topic evolution? I mean, how to know which topic in window 2 changes to topics in window 3, if we get more than 2 topics in window 2.

I think I know this answer.
What the authors mentioned in their paper is not a classical topic evolution, but a way to track the evolution of a dynamic topic.
According to the evolution, we can obtain the relationship between a dynamic topic and window topics instead of how a dynamic topic changes over time.
