They are, and the international version of the Moto G will have HSPA+ in refarmed areas, and EDGE service elsewhere. My Motorola Razr i has the same band support as the international Moto G, and I get HSPA+ in a lot of places in Boston but not all. Whereas my wife's penta-band Galaxy Nexus gets HSPA+ everywhere. What's confusing is that the US GSM version has the 1700 band, but not the 2100 band, and T-Mobile to my knowledge requires 1700/2100 (everywhere) or 1900/2100 (areas that have been refarmed for iPhone support).
