I *think* what is trying to be communicated is that if the *actual* shutter
speed (determined during exposure) is faster than 1/60, the flash will not
fire but a correct exposure (according to the OTF meter) will be made with
ambient light. If you set your aperture so the shutter speed indicated is
just 1/60 there is a chance that you "crossed the line" just a touch,
preventing the flash from firing. By selecting an aperture that results in a
displayed shutter speed of 1/30 (or even slower) pretty much guarantees that
the flash will fire. The shutter speed used will still be 1/60. This applies
to the OM-4(T(i)), OM-2S, and OM-2n (probably OM-PC, too). In fact if you
want to synch at a slower shutter speed you need to go into manual moe on
these cameras. I believe the original OM-2 is an exception to this, and will
keep the shutter open as long as is necessary for correct exposure after the
flash fires.
