In 8086 maximum mode, RD(read) signal is generated by 8086 itself. Why??

In maximum mode, bus controller 8288 generates controls signals like ALE, WR, DEN, DT/R etc. But RD(read) signal is generated by 8086. What is the reason for this??

Because the '86 is the only chip that knows when it --has-- read the bus data.
