You are forgetting that Get reads .m files (sometimes known as package
files), not notebooks. However, in 6.0 .m files can be edited almost as
if they were notebooks and non-code information such as headings is
stored in the .m file as comments.
Note also, that if you open a notebook and evaluate it, and then open
another and evaluate that also, the second evaluation will use any
relevant definitions from the first one.
