The original contributor says ""on the engine fan like the Harrier"". ""On the engine fan"" is specific to the front nozzles (he's not including the exhaust nozzles, they are not ""on the fan""). He mentions this in the same breath as lift fan, which is also ahead of cg, and lift engines, which on the only other operational VTOL YAK-38 were ahead of cg, ie all arrangements for lift ahead of cg.

The second part of the sentence refers to what's done with the engine exhaust, ie lift behind the cg (Pegasus similar so he didn't mention). We don't need to change that.   "
