Precentage penetration is multiplicative, not additive. What it means? It means 50% from Last Breath and 35% from Last Whisper gives 67.5%.

Now, it's 50% of BONUS armor so actual value is even lower. My guess, without any additional math, is that Last Whisper on Yasuo increases his armor penetration after ulting by 10-15%.
