My totally unofficial, but unambiguous interpretation of the writings of the GDC.

An appendage is considered a single appendage if, during its normal extension for usage outside the frame perimeter, all appendage components which intersect the frame perimeter projection are contiguously connected entirely outside the frame perimeter projection.


This would allow a 'fork' like appendage to not break the rule when only the tines of the fork are intersecting the frame perimeter during its deployment, but the normal usage of the fork appendage would need to be such that the portion connecting the tines must also be out of the perimeter projection as it is used.

And I don't think it matters if one tine of the fork is used to manipulate balls, and the other tine is used for moving the bridge -- multipurpose appendages are fine.
