Weird Gangplank bug

So, I was bored and wanted to see what it would look like if you built titanic hydra on gangplank. Everything was going as expected, the cone was coming from behind the target you q, and behind your autoattacked target. Then I q'd a barrel.

For whatever reason, if you q a barrel as Gangplank with Titanic Hydra it will project the cone not from the barrel (like Ravenous Hydra does) but actually from Gangplank himself. Whichever direction you are facing, the cone will be projected. This happens with both the passive and the active.

I would include pics/video but I am a scrub and am bad at doing such things.

EDIT:

Many thanks to Swizzle for taking pictures and researching it more thoroughly http://boards.na.leagueoflegends.com/en/c/gameplay-balance/1zj84qYe-gangplank-bug-with-images
