Please clarify me on the below doubts

There are 3 methods of current sensing
1. Inline current sensing
2. Inverter leg current sensing
3. DC Bus current sensing

In the Inverter leg current sensing suppose i sample the currents at every 50us for FOC (field oriented control) the currents will be the instantaneous values of the sine currents used for driving the motor. Am i correct?

I have just drawn a diagram representing the instants and the values of currents it reads. Is my understanding correct?
