Consider a case where I've got trees with prefix length 32 and 0.

So, we start out at 32.
We check the exit condition (even for the first iteration)
We don't exit.  So we look at trees[32]
We subtract 1 from I.
We keep going.
Let's look at i = 1.
we check the exit condition; 1 != 0 so we continue.
We check trees[1]
We subtract 1.
We check the exit condition
0 == 0 so we exit and never consider trees[0]
