No. They would have given it the reach property if it did... and I believe it unlikely to retained the ability to be thrown if it had been intended as a reach weapon.
In Player Companion Varisia Birthplace of Legends, where the weapon 1st appeared, the table says the Totem Spear Range 10 ft yet it also is classified as an Exotic Two-handed MELEE Weapon. That is confusing. Either it has range, or it has reach. One or the other. Hard to tell, though.
