Hi J,
Yes, as John noted above, one is before CAT and one is after CAT for same side of car (same engine bank) grey to grey and black to black as you show above is correct.
If you think they are reversed at their attachment point on the exhaust just read the part number off the barrel of the sensor and look it up in the catalog or a vendor website.
