From the GE web site: - Branch/Feeder AFCI
A Branch/Feeder AFCI has the ability to detect and neutralize a parallel arc fault, which is the unintentional flow of electricity between two separate wires. There are three types of parallel arc faults: line-to-line, line-to-ground, and line-to-neutral. The Branch/Feeder AFCI is permitted by the 1999-2005 NEC® Code.
Combination AFCI
GE's Combination AFCI delivers 5 kinds of protection:- Parallel protection – Just like its Branch/Feeder counterpart, Combination AFCI can detect and neutralize parallel arc faults
- Series Protection – A series arc fault is the unintended flow of electricity over a gap within a single wire. These arc faults were not detectable until advanced technology allowed the development of the Combination AFCI breaker.
- Ground protection – Arcing between a single conductor and a ground line
- Overload protection
- Short circuit protection
The 'old' AFCIs only detected an arc between two wires, line-ground, line-line, and line-neutral. The new ones detect an arc within a single wire (loose connection).

Also, the ITE (I hope other manufacturers have this feature or are working on it) combination breaker has LEDs to indicate what type of fault it is.
Oh yeah, the other difference is the combo unit is about $10 more.

AFCIs also protect against the use of some vacuum cleaners as well.

ITE? I'm assuming you mean Siemens/Murray.
