For large enough values of x, only the first few terms of this asymptotic expansion are needed to obtain a good approximation of erfc(x) (while for not too large values of Erf has the continued fraction (32) (33) (Wall 1948, p.357), first stated by Laplace in 1805 and Legendre in 1826 (Olds 1963, p.139), proved by Jacobi, and rediscovered by Ramanujan (Watson Error Function Excel Washington D.C., USA; New York, USA: United States Department of Commerce, National Bureau of Standards; Dover Publications.

So it remains to explain the normalization in $y$, and as far as I can tell this is so $\lim_{x \to \infty} \text{erf}(x) = 1$. For |z| < 1, we have erf ⁡ ( erf − 1 ⁡ ( z ) ) = z {\displaystyle \operatorname − 7 \left(\operatorname − 6 ^{-1}(z)\right)=z} .
