Not necessarily. It's why being clear and concise with an order is important. If I tell a house elf I want him to clean a room, but I don't specify when it must be cleaned or when it must be cleaned by, it isn't disobedience if he chooses to wait to do it until later. If there were clarity in my order, there'd be no room for interpretation, and any interpretation on the part of the elf could be seen as disobedience. I could also tell my elf to "get out" and unless I specify where I want him out of, he could leave the room, my presence, or the house. If I told him to get out of the room, and he left not just the room but the house, then that would be disobedience as I did not tell him to leave the house, just the room, and he thought to be clever by leaving the house as that would technically also be leaving the room since he disappeared from the room as far as I could see. True, it isn't a huge disobedience, but it would still be disobedience. Though the best way to get the elf out of the room but keep him in the house would be to tell him to go to his room until he's called for or for a set amount of time, and that he should go there immediately to avoid him deciding to go there later after he's done something else and disobeyed that way.
