In near absolute alcohol, the peptides that make up the cell wall coagulate and this eventually creates a barrier against the alcohol. In 70% alcohol, this effect is slowed and due to the dilution from the distilled water; allowing the alcohol to penetrate into the cell and kill the microorganism.

Why this concentration is considered to be more effective? Because in mostly laboratory uses, we use 95% alcohol solution for surface sterilization.
