I hope this is helpful:
The following is how a gas burner stovetop works. It makes no difference if the stovetop has a pilot or electronic ignition-
First of all, we’ll focus on three components; the burner, the pilot or ignitor, and a metal tub that runs between them without touching either the burner or pilot.

Burner
Here's a side view of the burner, as seen from the metal tube:
___________

| o | <-- note the two holes that face the open end of the tube.
|___o___|
1) When you turn on the gas, gas flows thru the holes at the burner top. A small amount also flows thru the small hole(s) that face the metal tube.
2) If pilotless, the electronic ignition sparks.
3) Gas flowing down the tube ignites, either from the pilot or from the sparking ignitor.
4) The fire follows the gas to its source (the burner) and ignites the gas pouring from the holes at the burner top.
5) Since the fire consumes the gas faster than it’s flowing from the tube, the flame doesn’t remain burning at the end of the tube next to the pilot. Instead, the flame at the bottom of the burner retreats to the hole(s) in the burner next to the tube.
Conclusion:
Although the burner’s flame is initially ignited by the pilot, the pilot and burner are two separate flames after ignition.
