This falls back on the high school theory of "work".....if you put a load on a rope with a block and tackle pulley arrangement (say first gear) and then you(the engine) pull on the rope it is fairly easy to move the load ( the vehicle) .....but if you eliminate all the pulleys (high gear) it removes the mechanical advantage you had putting the full load of what you are trying to move on you (the engine) so it has to "work harder"....

An engine won't produce it's full power until it needs to, so even at full throttle maximum torque won't be achieved until the engine sees a full load where it is required to do the most "work"....most dyno rooms used by the OEM's in the old days where called "load cells" because that is the only way to get a true measure of an engines power....

So to answer your question it is because the engine has to work harder in 4th gear than it does in 1st,2nd, or 3rd is the reason for the clutch slippage....
