No, the sideband components will extend beyond the edge of the phone band segment. 75-meter phone band for Extra class is 3.600-4.000 MHz. LSB extends 3 kHz below carrier, so 3.601 - 3 = 3.598 MHz, which is below 3.600 MHz band edge. For amateur radio operators, this is important for band compliance. Understanding this helps ensure legal operation.
