That’s a very misleading account of what happened. Georgia attacked South Ossetia in a full scale, pre-planned operation with the goal of seizing the whole territory. The idea that Georgia attacked SO spontaneously in response to some provocation is false.
It most certainly is not false. There were road side bombs, attacks on Georgian police, attacks on Georgian villages, by "South Ossetians." The Russians then accused Georgia of "genocide" when the Georgian military responded, and then promptly began the murdering.
