This alignment would be maintained even if the separation between the two is extended via tidal interactions. (alma-telescope.jp)
Observation, and theoretical evidence suggests that the LMC and SMC have been greatly distorted by tidal interaction with the Milky Way as they orbit around it; streams of neutral hydrogen connect them to the Milky Way and to each other, and both resemble disrupted barred spiral galaxies.

Since hot Jupiter exoplanets are «phase locked» by tidal interactions (that is, the same side always faces the host star, just as the same side of our moon always faces us), there will be a large flow of heat from the highly irradiated «day side» to the cooler «night side». (wasp-planets.net)
