thakis added a comment.

Yes, that's my understanding. (I'm not super familiar with this code either.)

The line was added in the change that added -Wimplicit-fallthrough 
(84837d5b5aa0d), and all the -Wimplicit-fallthrough tests still pass with this. 
Chances are it was unnecessary back then too.

(`addStmt` is from ea9fcffe035d, way older.)
