No, it's that 'same attack repels each other' thing. Like BLAME's hypergravity gun or other particle-based attacks, you can't just emit something and expect it will go in straight line, not dispersing into the air. Before the attack took place, you'd need to fire something to 'guide' the attack, like the channel/path of which lightning traces while it struck.
In this case the two 'paths' interfered with each other and causes a double miss.
