It sure does--as a result of photosynthesis. However, when the algae rises to the surface of the pond, it blocks out light and prevents sub-surface plants from photosynthesizing and creating oxygen. While this does result in oxygen in the upper echelons of your pond, the layers below become increasingly oxygen deprived.Over time this begins to kill the pond's ecosystem and can suffocate fish during pond turnover.
