Just because it does not seem to make sense, does not
necessarily mean that it's wrong.

My point isn't that something not making sense means it MUST be wrong, just
that it's a suggestion that it probably is.

For one, you
can't increase your load factor (and thus lift) without either increasing
thrust or decreasing airspeed.

I don't follow you. He can increase load factor only by
increasing bank angle unless you want to leave the steady
state constant speed turn regime he's using here.

My statement isn't about HOW to increase load factor. It's about the
consequences OF increasing load factor.

He's not talking about changing lift or bank angle.

Sure he is.

He
wants a steady lift equal to twice the aircraft weight at
sixty degrees of bank.

No. He starts with straight and level flight, and then considers what
happens when one enters a 60-degree bank. That's the initial condition for
the problem.
