Chessical: No! Apart from a mutual blunder on move 65, the endgame was only lost on move 99! The game illustrates a very practical and useful R v R+2 P's endgame, after we have also enjoyed the initial fireworks.
Here are other quoted text book examples:

Tartakover and du Mont in their "500 Master Games of Chess" give a 21 move version. This appears to be someone's analysis of a possible combination. This is the full game.
Spielmann plays the Moller attack which was only some 9 years old at the time. Duras, gets a worse position but then fight s back into the ending.
12...0-0?!, the book move is 12...Bxg5. Duras is too daring, he allows his K-side pawns to be disrupted for complications, that do not turn out to be in his favour.
11...0-0 12.d6 cxd6 13.Bf4 d5 14.Bxd5 Nxd5 15.Qxd5 d6 16.Rae1 Be6 17.Qxb7 Bxa2 18.Ra4 Be6 19.Rxa7 Rxa7 20.Qxa7 Bxb2 21.Ng5 Qf6 0-1 is Salwe-Rubinstein, Vienna 1908.
20....Rd8 20...h6! 21.g3 (21.Bb5 Nf4) creates a much more secure position.
22.Re8 Rxe8 23.Bxe8 Kf8 24.Bxf7 Ne7 25.Be6 Bxe6 26.dxe6 is a strong alternative.
22...Nh8?!. Instead 22...Nf4!? would keep Black in the game 23.Ree7 Rf8= (23...Nxd5? 24.Rxf7+! Kh8 25.Rh7+ Kg8 26.Rcg7+ Kf8 27.Nh4
24.Bd3!? would have better maintained the initiative, now Duras is back in the game.
Not 26...fxe6 27.Rh7 f4 28.Rxh6+ Kf5 29.Rxb7 winning
27...Rad8?, 27...a6!? would have avoided the game continuation after which the advantage swings back to Spielmann.
41...fxg2 42.Nf3+ Kh5 43.Rd8-+ Nh4 44.a7 Nxf3 45.Rd1 Ra2 46.Kxf3 Rxa7 47.Kxg2 with thge same type of ending (disconnected f and h pawns). This may be theoretically drawn, but is very hard to play for the defender. Duras would use one of his pawns as a decoy to Q the other to try to create a Lucena position.
51...Rxf3 52.gxf3 Nd4 53.Rb6 Nxf3+ 54.Kg3 is not enough to win.
65.Rb4?? is a tired fingerslip of a blunder. Both players miss the loss of the R by 65.Rh4+. Speilmann has defended the ending well so far.
99.Rf4?? Spielmann makes a fatal blunder after achieving a draw. Any legal K move would have been sufficient.
For the record the winning process is: 99...Kg5 100.Rxf5+ Kxf5 101.Ke3 Kg4 102.Kf2 Kf4 103.Ke2 Kg3 104.Kd3 f5 105.Ke2 f4 106.Kf1 Kf3 107.Ke1 Kg2 108.Kd2 f3
