Maybe it's a holdover (leftover?) from the early EX250 days (like the '86 to about '00 timeframe) when the alloy used in the cylinder heads was softer, which meant the valve seats were softer and the valves would really bed themselves in quickly.

After the first couple of valve adjustments these softer cylinder heads would stabilize somewhat.
