In this position, the 5-way switch functions like a normal Strat, with one volume and one tone control. In its full-clockwise position the blender control does absolutely nothing, and in fact makes itself disappear from the circuit so as not to load the circuit (think true bypass). The blender control affects either the neck or bridge pickup. But since this control is a variable resistor, rather than merely switch a pickup on or off, it allows the player to blend a pickup into or out of the mix, like a volume control would do. Rather then use a switch, he uses the bottom tone control to function as the switch.

Many players over the years have added switches to Stratocasters to allow this combination, and the switch is usually a push/pull pot or a mini-toggle switch (manufacturers - including G&L - have offered this as stock wiring on guitars). Telecasters allow players to select the neck and bridge pickups together, but Stratocasters don't.
