I'm not sure what kind of an explanation you are looking for. If it's a mathematical proof using a series of equations of aerodynamic principles, you might start here:
Pilot's Web The Aviators' Journal - Load Factor
But the bottom line is that the quoted language from your post is essentially incorrect, although I'm thinking that you probably know that since it's pretty basic that stall speed increases with load factor. The correct statement would be
Now, this aircraft was doing 300 kts - nowhere near its unaccelerated max gross weightstall speed at 1Gof 91 kts.
If you follow the equations in the article down, you ultimately get to the relationship between stall speed and load factor:
Accelerated Stall Speed = Unaccelerated Stall Speed X Square Root of Load Factor.
Your scenario involves an 11G load factor. SqrRoot of 11 is 3.32. That multiplied by your postulated 91 kt unaccelarated stall speed gets you a stall speed at 11G and max gross of just a hair under 302 kts.
