Not enough context given.

In general, "same voltage domain" would mean: "parts of a circuit supplied from the same source" or "parts of a circuit supplied by the same regulator" or "parts of a circuit supplied by the same filter" or "parts of a circuit connected to the same GND potential"

Typically this concept is applied to VLSI or FPGA design as it relates to different sections of a chip that are supplied with power on separate rails. A mixed-signal design, for instance, may use a +15V to -15V dual-rail voltage domain for its op-amps, while also having a 3.3V domain for digital logic. Bus adapters or voltage converters are used to interface signals between domains.

Yes, to me "same voltage domain" means points in a circuit which have a common point from which voltages can be measured. Two circuits which are floating with respect to each other are not part of the same voltage domain and you cannot measure voltages between the two circuits.
