Add a branch-after to this cleanup scope.
A branch-after is a branch from a point protected by this (normal) cleanup to a point in the normal cleanup scope immediately containing it. For example, for (;;) { A a; break; } contains a branch-after.
Branch-afters each have their own destination out of the cleanup, guaranteed distinct from anything else threaded through it. Therefore branch-afters usually force a switch after the cleanup.

Add a branch-through to this cleanup scope.
A branch-through is a branch from a scope protected by this (normal) cleanup to an enclosing scope other than the immediately-enclosing normal cleanup scope.
In the following example, the branch through B's scope is a branch-through, while the branch through A's scope is a branch-after: for (;;) { A a; B b; break; }
All branch-throughs have a common destination out of the cleanup, one possibly shared with the fall-through. Therefore branch-throughs usually don't force a switch after the cleanup.
