Your thousands of hours aside, this is simply an incorrect statement.
A barrel roll requires flying a loop and you can't fly a loop at 1 G.
It sounds like you are describing an aileron roll.

You can't even do an aileron roll without exceeding 1G.
Small g's sure, but you gotta go 1 to do just about anything.

Yes, for an aileron roll as you have to raise the nose at the start.
However, a slow roll should be able to be flown at 1G throughout, but it
would probably take someone of Hoover's (or Dudley's) skill to do it.
If you kept the center of mass of the airplane on the straight and level
track you are flying at the start, it would be 1G. The 1G wouldn't
always be positive with respect to the top of the airplane, however, so
I guess I should say |a|=1G :-)
