Yes i think there is a rational reason. Check this:

int a[] = [1,0,0];
int b[] = [0,1,0];
int c[] = [1,1,0];

bool ab = a[] < b[]; // False.  a[0] > b[0]
bool ac = a[] < c[]; // True.  a[0] == c[0] but a[1] < c[1];

writeln(ab);
writeln(ac);
c[] = ab; // <-- assign!

You see? Your code do this:

a[] = (b[] < c[]);
