2 amps added in phase with 2 amps equals 4 amps flowing
in the same direction.

You mean both directions. AC doesn't flow in just one direction. That
would be DC.

Instantaneous, Jim, instantaneous. AC flows in one direction for 1/2 cycle
and flows in the opposite direction for the other 1/2 cycle. A 2 amp phasor
at zero degrees added to a 2 amp phasor at zero degrees equals 4 amps at
zero degrees, flowing in the same instantaneous direction as the instantaneous
phasor components. When the two component phasors are at 180 degrees, they
and their sum are flowing in the opposite direction.
