No, if I understand Rune correctly, he means if you call it several times 
with different, but somehow linked to each other, pairs of values, the 
resulting "random" values should NOT have a visible link to each other.

example: 

#declare R1 = random(1,5);   
#declare R2 = random(2,6); 
#declare R3 = random(3,7); 
#declare R4 = random(4,8); 
#declare R5 = random(5,9);

#declare RT = random(1,2);

now the resuling values Rn (n=1...5) should not have a visible link to 
each other (although te input values are obviously linked) and RT = R1.
