Time and time again, DmBrandon has amazed us how many times he can have these "bursts of passion" in his gameplay. DmBrandon is a considerably well known figure in the SMITE community and has constant outbursts of anger on his personal stream, where he will usually follow that anger up with in-game toxicity. He has responded to accusations and recent anger here. 
I think it's best explained by this user comment on reddit.
