From this position:

I am confused. If white scores 80% against the novel Ne4, why should black investigate Ne4? Perhaps I am missing a previous thread.

From this position:
[D]r1bq1rk1/pp3ppp/2n1pn2/2pp4/2PP4/P1PBPN2/5PPP/R1BQ1RK1 b - - id "NNSSL.035";

pm b6 Qd6 dxc4 Qc7;
The above should be:
pm b6 *Qc7* dxc4 Qc7;

The score is about 50%
I only have the corrected pm moves. ChessBase has them plus Re8.

I analyzed this position using Horizon and it likes Ne4, even after 10 minutes. I would trust the book's judgement to Horizon analysis, though...

Perhaps he means that Black scores 80%?

White scored 80% in the games that Dann posted.
