Sleep: board constantly resets when RST and D0 tied

Hi,
I new to ESP8266 boards. I have a NodeMCU board and I'm using the Arduino IDE. When I tie the D0 pin with the RST pin, the board constantly resets.

I'm not using D0 (GPIO 16) for anything in my sketch. I'm following the basic sleep example here:

You still need a PullUp to VCC on RES pin.

Pullup resistor on the RST is default on the module nodeMCU 1.0 or am I wrong?
