Getting Tier 3 units in stage 1-2, at level 2.

Patch 9.18 states:

" We’ve made some minor adjustments to how likely which tier champions will appear at a few different levels. We’re hoping these make clearer early, mid, and late game phases. "

• Level 3 by Tier: 65%/ 30%/ 5%/ 0%/ 0% ⇒ 70%/ 25%/ 5%/ 0%/ 0%
• Level 5 by Tier: 37%/ 35%/ 25%/ 3%/ 0% ⇒ 35%/ 35%/ 25%/ 5%/ 0%
• Level 6 by Tier: 24.5%/ 35%/ 30%/ 10%/ 0.5% ⇒ 25%/ 35%/ 30%/ 10%/ 0%
• Level 9 by Tier: 10%/ 15%/ 35%/ 30%/ 10% ⇒ 10%/ 15%/ 33%/ 30%/ 12%
• All other levels remain the same.

...which means, at level 2, Tier 3 units should still have 0% drop rate.

So, care to explain why someone managed to grab and in stage 1-2, at level 2?
