absolutely

you are 100% correct, I should have said "exact same framing"

some more information to help you

If you were to shoot a subject 15 feet away with a 70mm lens on dx in
order to take the exact same shot with a 55mm lens you would have to
move 3.2 feet closer and stand 11.8 feet from your subject (basically
about 1 normal step)

If you were to shoot a subject at 15 feet at 17mm in order to get the
same shot with a 24mm lens you would have back up 6.2 feet so that
you were standing 21.2 feet from your subject

Actually you can't take the exact same shot with a different focal
length lens by moving closer or farther away. When you move you
change the perspective.

Thus, if you were to shoot a subject 15 feet away with a 70mm lens
on dx in
order to take the exact same shot with a 55mm lens you would have to
stand in the same spot, take the shot, and then crop the one taken
with the 55mm lens.
