Wriothesley normal attacks buffed even below 50% HP

[starrynte]

When Wriothesley uses skill, the normal attacks should only be buffed while he is above 50% HP (if I understand correctly). However, currently they seem to be buffed even below 50% HP, although no HP is consumed.

Sample config:

wriothesley char lvl=89/90 cons=0 talent=9,9,9;
wriothesley add weapon="apprentice" refine=1 lvl=90/90;

options iteration=1;
target lvl=100 resist=0.1 hp=999999999;

active wriothesley;
hurt once interval=0 amount=30000,30000;
wait(600);
wriothesley attack:5;
wait(600);
wriothesley skill, attack:5;

The attacks after skill should have the same MV as without skill, but they appear to be buffed.
