My analysis, using mostly Fritz, agrees with your assessment:
1.Re8!
[White must avoid 1.Rxf7+? Kxf7 2.Kxf3 b4 3.Ke4
(3.e4 Ke6 4.Ke2 Kf6 5.Ke3 Ke7 6.Kd4 Ke6 7.e5 Kd7 8.Ke3 Ke7 =)
3...Ke6 4.Kd4 Kf6 5.e4 Ke6 6.e5 Ke7 7.Ke3 Kf7 8.Kf3 Ke7 =]
[1.Re6 Rf6 2.Re8 Kf7 3.Re5 b4 4.e4 Kf8 5.Rf5 Ke7 6.e5 Rf8
(6...Re6 7.Kxf3 Ke8 8.Ke4 Ke7 9.Rf3 Ke8 10.Rf6 +-)
7.Kxf3 Rd8 8.Ke4 Rd5 9.Rf6 Rxc5 10.Rxh6 Rc3 11.Kf5 Rxb3 12.Rxc6 Rf3+
13.Kxg5 Rxh3 14.Rb6 ±]
1...h5
[1...bxa4 2.bxa4 Rb7 3.Kxf3 +-]
[1...Rd7 2.Ra8 +-]
2.Re6 hxg4 3.hxg4 bxa4 4.bxa4 Rb7
[4...Rf6 5.Re7+ Rf7 6.Re5 Kg6 7.Re8 Kg7 8.Ra8 Rb7
(8...Kf6 9.Rc8 Ke5 10.Rxc6 Ke4 11.Re6+ Kd5 12.Rg6 Ke4 13.c6 Rc7
14.Rf6 +-)
9.Kxf3 Rb4 10.Rxa5 Rc4 11.Ra7+ Kf6 12.Ra8 Kf7 13.a5 Rxc5 14.a6 Ra5
15.a7 Kg7 {else White plays Rh8} 16.Ke4 Ra4+ 17.Ke5 c5 18.e4 c4 19.Kd4 +-]
5.Kxf3 Rb4 6.Rxc6 Rxa4 7.Ra6 Kf7 8.c6 Rc4 9.Rxa5 Kf6 10.Ra6 Ke5 11.c7 Rxc7
12.Rg6 Rf7+ 13.Kg3 Ke4 14.Rxg5 +- {I think}
