Just thinking: Possibly because that conditional tries to detect whether
the following code block applies or not; the code knows how to handle
"version 2" data, and that happens to be the current version, but that's
just because there is not a "version 3" (yet).
Let's say, in the future, there is a version 3; the code could become:
if version == 3:
# new code to handle version 3 data
elif version == 2:
# code to handle version 2 data
# this is the current contents
else:
# error message, as right now.
