That is correct. Here's proof, with our latest development build:

C:\Temp>type meow.cpp
#include <stdio.h>

void f(int) {
    puts("Standard two-phase!");
}

template <typename T> void g(T t) {
    f(t);
}

void f(double) {
    puts("Microsoft one-phase!");
}

int main() {
    printf("%02d.%02d.%05d.%02d\n", _MSC_VER / 100, _MSC_VER % 100, _MSC_FULL_VER % 100000, _MSC_BUILD);
    g(3.14);
}

C:\Temp>cl /EHsc /nologo /W4 /MTd meow.cpp && meow
meow.cpp
19.00.24229.00
Microsoft one-phase!
