Agreed.

In a _coordinated_ turn, which necessitates a bank, or roll, on
longitudinal axis, there will be no such lateral displacement as you
predict, however, turbulence may produce some if that. If the roll
rate is brisk, there may be some increase in G felt by passengers in
the rising wind, and decrease in G felt by those in the descending
wing, but with today's computerized fly-by-wire control systems, all
these concerns could be largely eliminated in nearly all cases.
