I assume you mean 19.R1f3 and 20.R3f4

There are more possible lines

For example 17...hxg5 18.Raf1 Qb7 and I do not see more than a draw for white
after a line like 19.R1f3 g4 20.Qxg4 Qb1+
Draw may be a good result for white so even if white has no more than a draw it
does not prove that the test is wrong.
