I ask, because I never used your flip trick for k a negative integer.

Wolfram's answer is correct.
Why would you expect W-1(-1E-330) == W+1(-1E-330) ?

x + ln(x) = ln(a) + 2*k*pi*I

With k = ±1, same a, RHS have difference of 4*pi*I ! Of course solved x is different.

I already explained why flip trick don't work in this case (see my previous post)
