It's not store-and-forward vs. cut-through. It's whether or not the switch acts as a layer 3 device, or a layer 2 device. If it acts as a plain old layer 2 device, it can pass the packet, unmodified. As a layer 3 device, it modifies the layer 2 headers, and the TTL. As a layer 3 device, it can still cut-through.
