Mistake in the language tour?

[Tactile-Taco]

`subscript min_inout(_ x: inout Int, y: inout Int): Int {
inout { if y > x { &x } else { &y } }
}

public fun main() {
var (x, y) = (1, 2)
&min_inout[&x, &z] += 2 //<---------------------------------shouldn't this be &min_inout[&x,&y] += 2 ?
print(x) // 3
}`

Yep, good catch.
