If you improperly downshift into 2nd at say 80 MPH and release the clutch, the engine will over-rev mechanically as it would with any car. However, I don't think the actions of SRM itself (pretend you put it in 2nd at 80 MPH but catch yourself before you let out the clutch) will cause an over-rev because there is no mechanical force driving the engine beyond its capabilities.

You're absolutely right, but if you engage the clutch on an SRM downshift you're still forcing the engine speed to match the transmission (over-rev). I suppose if you catch yourself in a bad shift before engaging the clutch, you may not go past redline. However, bouncing off the rev-limiter isn't a great idea. The 'problem' with an over-rev downshift exists with or without SRM. The OP was just asking originally if SRM will allow gear-skipping downshifts. It absolutely does...I just enjoyed a flawless SRM-assisted 6-3 downshift on the highway today and sucked the doors off a guy going slow in the left lane  .
