XTK simulation shows indeed almost the same signal at the receiver pin, but a
different situation at the driver pin. A higher value of the trace impedance
determines higher overshoot at the driver pin.
This overshoot will generate crosstalk and EMI problems. Note that close to the
driver pin is always a via to get the high speed signal on the internal layers.
This via will amply the effect.
Have fun,
