Multiple Xerath in Ascension? + level 7 token problem

So to start i was playing some Ascension games and i saw Tahm Kench literary EATING the big Xerath and when he spites it out, there is 2 of them...... ITS NOT DONE YET! He can eat MORE! so he was duplicating the big Xerath in the middle of the map. He just stayed in the middle the whole game spitting more Xeraths. Is the some kind of weird interaction or its just a Khazix (haha get it? khazix is a bug ha.....ha......no?....ok imma stop now). Thx 4 replying :). Oh and also for the level 7 tokens, i am a level 6 jax and i got an s and got a level 7 token. i got a another s ( in another round) and i didn't receive a level 7 token. did i do some thing wrong??? i don't know any thing that can cause this, since i have a level 6 jax i should get a toke for level 7 right? can i rito answer this please?
