. . you `could` say that in decomress from typical cruise alt - both altitudes will meet at about . . 20,000 - that would be for a eng 1 and 2 out situation (whilst you restarted the engines, or glided to a nice long runway for your landing . . .) in the 320.
For somethingelse that has caused the decompress then the outside altitude and cabin could meet higher up, naturally.
