I think this code fragment must be part of a "fail-soft" algorithm. The idea of fail soft is that you make sure anything that fails low returns an upper bound on the value, and you make sure anything that fails high returns a lower bound on the value, and you make sure the bounds you return are the best ones you can possible get without searching more nodes. The main thing is to initialise the value at the top of the routine to -infinity instead of the lower bound.
