That's right. In New Game Plus, the upgraded inventories from all vendors remain as high as they were from previous playthroughs. Vendor inventories can improve on subsequent playthroughs (by raising their affinities or giving Caxton/Madeleine Silver/Gold Idols), but they'll never reset to Stage 1 inventories.

For example if you gave Madeleine only a Silver Idol on your first playthrough, she'll continue to offer the upgraded Silver Idol inventory on your second playthrough. But to improve her inventory on the second playthrough, you can give her the Gold Idol to upgrade her sales offerings for the second playthrough and beyond.
