"What happens is that warm moist air is drawn into the next soffit vent

into the attic space where it can cause damage. Remember that soffit
vents
are normally air inlets. "

I guess that's theoretically possible, but has anyone ever seen it lead
to an actual problem? Bathroom fans are almost always on for a short
time, so any moisture that was introduced should dissipate pretty
quickly. I have a hard time believing that in actual practice, this
is really an issue. It's done on most of the homes here in NJ that
I've seen and hasn't been harmful.

I've got the fan vented thru the soffit. In cold weather the vented air
condenses quickly making it visible. It's quite obvious that it blows away
from the house and does not get sucked back into the adjoining vent.
