Yi and Tahm wierd interaction (Gameplay)

I was playing an Aram as Master Yi, and there was a Tahm Kench on my team. At one point, Tahm devoured a enemy Bard, whilst the same time, I Q'd (alpha striked) Bard. For some reason I got stuck inside Tahm, was still targetable and killable. It happened pretty fast though, and I got no video/pictures of it.
