Should "touch point" districts be considered continuous?

As Lewis already pointed out (tho how he knew that I don't know) the guidelines South Carolina follows allow for them, but not with a double crossover.  Anyway, here's a little graphic to demonstrate.  (It isn't state law, but the Senate committee that did redistricting last time included it in their list of guidelines for acceptable districts.)

Allowed    |     A | B    |    ---+---    |     B | C    |

Prohibited    |     A | B    |    ---+---    |     B | A    |

Prohibited    |     A | B    |    ---+---    |     B | A    |

Isn't that what North Carolina has between two district's now?

Is that what BigSkyBob refers to as a "double-crossover"?

Or is that if there are two of the above between the same pair of districts?

Yes it's a double crossover, but as far as I know only South Carolina has redistricting guidelines that explicitly ban double-crossovers but explicitly allow touch point districts.

Indeed, SC would allow something like this:

   |   
 A | B
   |   
---+---
   |   
 B | C
   |   
---+---
   |   
 C | D
