THIS DOES NOT MEAN IT IS SAFE TO PLUG YOUR U.S. MAC INTO A 230V MAIN!!!!!!!!!!!

What this implies is that somewhere internal there is a switch (or solder
jumper, or something) that allows the supply to be set to one of the two
ranges mentioned. It does NOT say that you can plug it into 110V or 220V,
but not 150V. It does say that voltage is the only necessary setting, and
that frequency is not an issue.

I don't know what the SE internals are, that's your disclaimer. I DO know
from experience that this is typical marking of a supply intended to be
switched internally between two or more flavors or power.
