Zappa played the the moves with different order. First 4...Nf3 and then
5...Rag8.
that means your line with Qxg7 leads to:
1. Nf6+ gxf6 2. Qxf6 Kd7 3. Rad1 Bg7 4. Qxg7 Nf3 5.gxf3 Rag8 and now 6.Qxf7 is
the best but that leads to a worse position that my 4.Rxd4 does.....

Please correct me if i'm wrong......

PS:Notice that the 7. Qxf7 Qxg5+ 8. Rg4 Qd8 9. Re1 h5 10. Rxg8 Rxg8+ 11. Kh2 Rf8
doesn't work well due to the attack on the somewhat exposed white King....
