I assume by gravel he means washed gravel or stone? If it's true
gravel, ie stones mixed with sand, clay, etc then I don;'t see the
point at all. Even with stone, it doesn't sound like a good plan to
put a membrane between the existing stone, then more stone on top.
The water has no place to go and with an irregular surface to the
membrane, will tend to pool up in spots and stay there until it
evaporates.

Normally, just having the grade slope away from the house is
sufficient to move water away

It seems to me that he created the slope with the gravel. I agree the
whole concept seems a little half-baked.
