Auto attacks are calculated from the edge of you champion's model to the edge of the enemy you're attacking. Spells are calculated from the centre of your champion to the enemy's centre.

Annie has the same quirk, especially when attacking a large target like Nautilus or ChoGath. She can auto them freely but still have to walk an extra distance forwards to Q them even though they're technically both 625.
