My son if flying to MCT tomorrow and accepted a £120 WT-WT+ upgrade offer. He also paid £25 to choose seat 18B, which is showing as the first row in a three row (18-20) cabin. Isn't that a bit odd?

The route is normally served by a 4 class 777, which I would expect to have 5 or 6 rows of WT+ (21-25/6). The only 3 row config I can remember seeing is on a 3 class 777 (rows 12-14).
