Crankcase blowby exits the engine at relatively high velocity. Routing this into the oil tank allows most of the liquid oil to separate from pressurized gases/air. The oil tank provides an area that allows the blowby/oil mist flow to decrease so a smaller tank can further separate liquid from vapor.

Another plus 1 to not allow condensed H2o, raw fuel, other liquids, etc. to drain/return to the crankcase.
