I think it's fair to say that Carl, and Mojang in general, didn't understand him either. So the understanding was definitely mutual, even if the reason for that was almost entirely Julian's inability and unwillingness to talk about contracts and money, but also not wanting to hand that over to his agent. But at the same time it's pretty clear he was jealous of all the money he didn't want to talk about, and that he saw himself as a partner rather than a contractor.
