Why equatorial counter current is not on equator?

"The Equatorial Counter Current is an eastward flowing, wind-driven current which extends to depths of 100–150 metres (330–490 ft) in the Atlantic, Indian, and Pacific Oceans. More often called the North Equatorial Countercurrent (NECC), this current flows west-to-east at about 3-10°N in the Atlantic, Indian Ocean and Pacific basins, between the North Equatorial Current (NEC) and the South Equatorial Current (SEC)"

Why it's not on equator? Why it's not 4°S-4°N for example? What pushes it from equator in all 3 oceans?

Ocean currents are driven by temperature and the salt concentration profile, that changes due to evaporation of water.

The continents obstruct, and the seafloor restricts, the ocean circulation.

Surface waves are driven by the wind, and that alternates with the seasons, between the Tropic of Cancer and of Capricorn, summer and winter, north and south, about ±23.5°

Because it's just a name. You may as well ask "Why does the Canary Current start around the Azores a thousand kilometres north-west of the Canary Islands?"
