I'm pretty sure that's what he said. His entire block of code was:
---
int x;
if (x) {} // should work: compare x against zero
bool y;
if (y) {} // should work :o)
y = x;    // should not work, use y = (x != 0);
x = y;    // should not work, use x = cast(bool)y or x = y ? 1 : 0
---

So the declarations were still in scope ;).
