Both blademail and carapace should trigger off the same unit takes damage instance, so the order in which they are done shouldn't matter. Carapace's triggered heal wouldn't affect anything. There would need to be a replay confirming the weird result before it would be looked into further.
To the man who is confused. The results show the difference between your current hp and huskars current HP as a decimal (0.8 means you need 80% of his current hp, ie: you have 800 hp he has 1000 hp) in order to kill him when he ultis you
The calculations were started assuming that they are both at maxHP. I have no idea why I did that and about halfway through I realized that the math is fine for any currentHP. Understand I do these sorts of calculations very quickly and don't edit them much.
