If package foo upgrades from version 0.0-1 to 0.0-2 without changing
dependencies, apt-get upgrade will go ahead and upgrade it.  If
package bar upgrades from version 0.1-3 to 0.2-1, but version 0.2-1
also has a dependency on libbaz1 which wasn't previously installed,
APT won't do the upgrade (because libbaz1 would change from "purge" to 

apt-get dist-upgrade *will* go ahead and upgrade everything,
regardless of what the new dependency situation is.
