Right you are, but the Boxster is not a dry sump engine.
Porsche very carefully describes the M96 engine as having an "integrated dry sump". Much more a marketing description than anything else.
It lacks an external tank, and scavenge pumps typical of a true dry sump system. It relies on gravity to return the oil to the sump where it is picked up by the pickup tube and fed to the pressure pump to recirculate through the engine. It is in fact much closer to a wet sump system than a dry sump one.
The Boxster has had issues with oil starvation, especially with the early models in high g maneuvering. Updates to the baffling of the sump have lessened these, but not entirely, especially if you were to operate it at idle on an incline where the oil level can flow away from the sump and pickup, exascerbated by the low rpms of the oil pump itself.
