Or maybe it is to evenly spread the oil from the squirters to a larger surface area in the cylinder head rather than just dump oil straight onto the camshaft on one spot. You can view holes right below the baffle to allow oil to fall off. Typically, this leads to a damaged or scored camshaft from lack of oil.
I highly doubt it is to prevent oil from coming out. Why would one run the engine for any extended period of time with the oil fill cap off?
Good idea, bad idea, I dunno. YMMV.
Ask Nissan why they did it.
