Yes it is a bypass filter as in the oil BYPASSES the filter when it's PLUGGED, allowing unfiltered oil back into the engine to keep oil pressure up in a really bad situation.
The filter you show and I quote the Navy and Marine Corps: SER-002-99; Air Force: PM05; Army: VHM-- "The Bypass filtration is a system that provides high density, slow filtration (one to six quarts per minute at engine operating temperature) of engine oil without affecting the primary OEM filtration system. Bypass filters also remove solid contaminants down to 3 microns, control moisture content in oil, are compatible with all MIL-SPEC oils and extend oil drain intervals. Bypass filters are installed in the engine compartment of a vehicle or, nearby a stationary engine. The bypass filter is fed a slip stream of oil that bypasses the engine"
Internal bypass VS. Engine bypass, in the case of Mercedes the oil doesn't leave the engine.
A little different
