Evolution of logo through the years.

in Prometheus the logo for Wayland industries is a w w, then after they merge with Yutana it becomes an Egyptian marking, then sometime in-between alien in aliens, it was changed back into a W, now yellow with an interlocking Y, so why the Egyptian logo for that short period?
