The convention of letters VAB for voltage means the potential between A and B. Voltage is a potential measured with respect to another point in the circuit. For example VBE is the voltage between base and emitter. Ground does not have a specific "letter". So the convention of repeating letters is used, like VDD or VEE to refer to the point relative to ground. Using single letters in this context adds more confusion since Vs may refer to the voltage of a source "s" (which may be different than VSS if there are multiple sources in series, etc.) and not the voltage between a transistor's emitter & ground.

So the convention of repeating letters is used, like VDD or VEE to refer to the point relative to ground.
