Once it leaves the so-called main sequence and enters the red giant branch phase, it will begin a frightful growth in both luminosity and size, becoming, over the course of just 600 million years, 2,300 times as bright as today and 170 times its current diameter.
It's clear those guys had not carefully considered the red giant branch of the Sun's evolution.
