Can the STPM34 use two 120V channels to measure power delivered to a 240V outlet?

I'd like to use the STPM34 to measure power delivered on two 120V outlets. One outlet will use Red & Neutral, one outlet will use Black & Neutral. When the 120V outlets are not being used, I will use Red and Black on a 240V outlet.

My question is, if the two channels of the STPM34 are configured to measure both 120V outlets, when I run the circuit in 240V mode, would the measured and reported power/energy of the two channels summed together equal the power/energy of the 240V outlet?

The analog connections to the STPM34 would be as follows:

VP1 -- sense_red (scaled 120V Red)

VN1 -- Neutral

IP1 -- red_I_sense_P (current transformer secondary positive)

IN1 -- red_I_sense_N (current transformer secondary negative)

VP2 -- sense_black (scaled 120V black)

VN2 -- Neutral

IP2 -- black_I_sense_P (current transformer secondary positive)

IN2 -- black_I_sense_N (current transformer secondary negative)

Thanks!
