The article could use some additional discussion:
Such events would have been very common in a young planetary system, less so over time as orbits were swept.
Earth-grazer's less-violent collisions would be more compatible with the panspermia model than would surface-impacting meteorites or surface ejections. They also support both inward and outward transfer of biota.
