you can do either way as long the pipe is emt but i rather run real grounding wire from breaker box to the junction box from there you have to make a pigtail i know it is little tough to make a pigtail with #10 wire but it can be done .

this is my most common pratice to run full 4 wires even thru if run in emt i still do that because for safety reason if the emt do " break " you still have grounding protection there

Merci. Marc

p.s. double check your dryer connection on back of dryer where the electrical connection you will see a jumper band there take it off and run like true 4 wire [ most dryer and stove dont provide the plug anymore so watch out with this one ]
