He reviews the FE and makes that statement. The EL2 is the same exact meter according to minolta so Im deducing that what the FE does, the EL2 does.
He also mentions it a little on his review of the EL2 which is found

"My exposures are all perfect, from 1/1,000 to many seconds. In fact, it will make automatic exposures far longer than 8 seconds, even though it's only rated to 8 seconds on automatic.
When I have made 32 second automatic exposures they seemed a little dark, but that's because I forgot to compensate manually for
Velvia 50's reciprocity failure."
Heres a quote from his review of the FE at

Long Exposures
The FE's internal circuitry is analog, so it has none of the hard range limits of newer cameras with digital circuitry.
If you shoot scenes at night, the FE will meter and clock-off time exposures automatically. Forget newer cameras which require you to sit there like a dork holding a cable release while watching a wristwatch and holding a flashlight to see it all.
With an FE (or FE2 or FA), compose the scene, cover the eyepiece if your eye isn't on it, wind the self timer, and press the shutter.
The FE measures and locks the exposure, flips up the mirror, counts off about ten seconds, and then makes the time exposure automatically.
You don't need a cable release, and the mirror locks up and returns all by itself. It is way, way superior to any digital Nikon.
I've never had the patience to wait around and see just how long the Nikon FE will expose.
Out of curiosity, I loaded fresh A76 cells into an FE set to ASA 50 and, with the lens cap on in AUTO, pressed the shutter.
The shutter stayed open for 63 minutes, and then closed at ISO 50. Whoa!
I tried it again set to ASA 400, and the FE stayed open for 3 minutes and then 17 minutes. It will vary by temperature and the amount of light to which the FE was exposed a little while before you started the exposure. Remember, the FE is analog, and it's the leakage currents which are defining the long exposure times.
These times correspond to
LV -13 with an f/1.4 lens, which is about ten stops darker than normal night time.
These times are with a wide-open lens. The FE calculates even longer times if you stop down your lens!
The FE doesn't calculate corrections for reciprocity failure. Luckily, the lessened effective exposure with most film gives the darker results we want to make night shots look like night; otherwise night shots would look as bright as day."
