i think you got got it the other way around. looking at previous frames and jittering the image is what lets the renderer know what the geometry should look like in many positions so it prevents aliasing and prevents jaggies. but the accumulation of this information is what leads to ghosting, usually because it takes too many samples from before so they carry over to the current frame a bit too much.
there's always some ghosting with temporal methods even if you use the right amount of samples, it ranges from unnoticeable >>716150191 to extreme like >>716102695 depending on resolution and the complexity of the renderer and sample count
