It only works after a mistake
Black must play Nxd5 for it to work. This is an attacking idea, not a forced win. After 6.Nxf7 the position is very hard for Black to defend in practice, but a careful defender can survive. Black avoids it completely with 5...Na5.
How to avoid it
After 4.Ng5 d5 5.exd5, play 5...Na5 (the main line) instead of 5...Nxd5.
