No... conditional jumps uses the FLAGS to decide if the jump is taken or not... DEC affects the FLAGS.

The conditional jump uses whatever is the last condition generated (ie the flags, as fred said). In this case it uses the result of the preceding dec. Your code would work with the new push/pop, it's just slightly less optimal.
