I Think This Was The First Time This Jax Played Against Tryndamere... 

I asked myself the same question

The hit was registered before the flash so he was already in AA range and when Jax flashed since he didn’t cancel Aa it completed the AA animation. It’s why you don’t keep right clicking your target to fast at times. Especially when you’re expecting them to side step , blink , etc

this is youtuber special range

Found Jax

@@OneEyedManKingdomOfTheBlind look at that range again and tell me you wouldn't think the same thing 😩

@@TheWTFcakes it doesn’t matter. Once the auto animation starts, only losing vision will stop it. You can go to China and it will still hit you.

@@TheWTFcakes lol melee auto attacks cannot be cancelled by distance unless you lose vision. You could go to the moon and it would still hit you.

The auto attack wasn’t even in animation yet tho
