The way I see it if the two back wheels go forward and one of the front omni wheels go forward Does the robot go to the side? I just don't get it how does it move? i mean the omni wheels are not side ways and not being so wouldn't that just create a forward moving force if the omni wheel where to forward spin rather than a side ways force? Or are they on an axle and if so why not just put normal wheels there? or are they programed differently?

Omniwheels can and have been used on traditional N-wheel-drive systems to improve the robot's ability to turn; no holonomic movement is achieved. You might want to read this white paper on the topic.
