Surfaces seen through transparency or reflection aren't sampled in the GI prepass, but they will use nearby GI samples that were taken from above the surface (in this case the nearby trees and dry land), and at some distance from these samples the contribution falls off to 0. The path tracer doesn't use the GI cache on surfaces so it doesn't have this problem.
