It's not optimal wording (the same is true for damage descriptions and formulae listed for other abilities that can critically strike), but critical hits will deal 150% of normal damage (instead of 200% that critical basic attacks deal), or 200% with Infinity Edge  (instead of 250% that critical basic attacks deal with IE).

"Bonus critical damage" can be very confusing because it can sound like it includes the normal +100% damage of critical hits without IE, but it doesn't, it only refers to IE's bonus damage as well as that from critical damage runes.

The 1 in the brackets accounts for that normal 100% additional damage on critical hits.

Normally the above formula would work out as 0.5× [1+(2×0)] → 0.5×[1] → 50% extra damage, i.e. 1.5×normal damage with the ability

and with IE it works out as  0.5× [1+(2×0.5)] → 0.5×[1+(1)] → 0.5×2→ 100% extra damage, i.e. 2×normal damage with the ability
