You're right, I think the ranges used there are questionable but not completely retarded.

For this particular situation one future game is simulated. Villain is now the button and we are in the small blind. Starting stacks are now: button 1870/ hero 5560/ BB 6070.

Hand ranges:

Button push 25%
Hero call 20%
BB call 25%

Hero push 20%
BB call 10%

Now this future simulation lets the fold equity drop down in OP's hand.

List of equity in simulated future game:

Button wins blinds 35.51%
Button beats Hero: 31.37%
Hero beats button: 41.75%
Button beats BB: 35.23%
BB beats Button: 37.87%

Hero wins blinds: 37.34%
Hero beats BB: 46.36%
BB beats Hero: 20%

BB wins blinds: 35.89%
