Oracles are mapped to the foreignAsset but not to the specific pair. Pairs with the same foreignAsset (e.g. UniswapV2 and Sushi) will be forced to use the same oracle. Generally this should be the expected behavior but there are also possibility that while adding a new pair changed the oracle of an older pair unexpectedly.
