If you mean geographically, then no, that's not needed. What makes a region is that the clocks set correctly show, and have shown, the same time, alyways, since standardised times were introduced (or for definite inclusion in tzdb, since 1970) If two areas have always had the same local time, they can be represented by the same timezone (and would normally be so unless that looks to be by pure chance with no overriding reason it should be so). If the local time has ever differed (since 1970, and ideally, though we are not there yet, since standardied time) then they should be different zones.
So there is no requirement that a tzdb region be a connected space?
