It is better than analyzing forward if the program use learning correctly.
programs can avoid part of their mistakes of saying that a good move is a
blunder because it does not see deep enough.
If one player won by a combination that is too deep for the computer to see then
it may learn from the line about the combination and in this case there is a
chance that it is not going to consider the wining combination as a blunder.
There are cases when one line is not enough to prove the winning combination and
in this case the computer is going to still say that the wnning combination was
a blunder.
I think that it may be relevant mainly for analyzing correspondence games or
super GM games or computers games because in other games the players usually do
not see deep enough to see tactics that programs may miss.
