I think you misunderstood how the talent works. Read the description carefully again.
Hero has 100 hp and 100 mp.
He is damaged and he has 40 hp curently, which activates the "below 50%" part.
4% of 100 mp = 4 which equals to 4 hp/s.
Now, he has 120 hp, which is 20 health over the basic 100 hp.
120 hp = 6 x 20, meaning you have +6% of 100 mp = 6 hp/s.
So, you add 4% basic + 6% bonus = 10% total.
10% of 120 hp = 12 hp/s.
That's it.
