Assume you installed package foo version 1.0 and modified one of its 
files marked as a conffile[1]. On the next upgrades (say versions 1.1, 
1.2) nothing changes in the *packaged* file, so dpkg will just upgrade 
the package without any prompts.

[1] BTW, "conffile" and "configuration file" are not synonyms

Now assume you eventually upgrade to 2.0, which brings major changes, 
including some changes to the *packaged* conffile. In this case dpkg can 
not decide by itself what to do and will ask the system administrator 
during the upgrade.

This works good in most cases. Exceptions would be something like cups, 
which lets you modify a conffile through the web interface and then you 
get a conffile prompt.

Hope this explains,
