It will run as long as the condition is TRUE. The condition
is TRUE if x<3 OR y>600. So if one condition is false, it
is ok, it will still run the loop, as long as the other is true
since the test is an OR

It will stop the loop when both checks are FALSE.

That is what I thought you wanted. But if you want to
stop when one of the 2 conditions condition fail,
change it to

--------------------
x=2; y=603;

while x<3 && y>600
x=x+1
y=y-1
end
