Here's the message I received when I wrote to Jim Lee of Olympus. (Jim travels around the U.S. to various large camera stores giving Olympus camera classes. He's an Olympus tech wonk.)

Hi Leonard,
The new FL-50 R flash receives information from the E-3 pop-up flash. This is a Flash triggered system and not a wireless or IR based flash system. The pop-up flash has a range limit so the FL-50 R must be able to see the flash from the E-3 in order to fire.
From my testing, the pop-up flash did not interfere with the overall light value. Since it is giving you TTL reading it is very accurate even at a close range to the subject.
I hope this information helps you.
Best,
Jim
