But... why? How? That makes absolutely no sense.
You don't need DNI in any capacity to operate a matrix enabled device. It's just an object. A thing. If you have a commlink in your hand, it's doing its own thing entirely.
The way that paragraph reads, if you have a phone in each hand, no DNI, pure analog interface, and Google search taco stands in Touristville, only one of them works because you can only generate one persona with which to interact with the matrix.
Which... is... impossible. Machines don't work that way. There is no connection between you and the machine. There is no place that persona can possibly come from other than the device, because it is not you. It is not connected to you.
What the frag?
Not that it particularly matters, in this case. The idea is to take down the entire matrix in the area so no one can use it. It's gonna be a shotgun in your hands from that point, not a cyberdeck.
