It means that there seems to be a cost in doing state changes with OSG. GL state changes do not necessarily incur any cost - this is implementation specific anyway - whereas OSG state changes seem to always incur one, as even going through empty statesets does incur a cost.
NOOP assembly instructions seems like they'd be a good analogy to empty StateSets. You wouldn't little up your assembly code with unnecessary NOOP instructions and expect to not take a performance hit. Likewise, empty StateSets have a non-zero cost.
