That's called a cross arm. It's just what you do and has been done for over a 100 years that way. It's how they spread the wires out for 3 phase. You could run vertical 3 phase on a pole without a cross arm but it takes up too much space on a distribution pole. You'ld need like 60 foot poles instead of 45'.
