NoteWorthy will not automatically beam across a major beat. The time signature controls what a major beat is.
So we have this:!NoteWorthyComposerClip(2.751,Single)
|TimeSig|Signature:2/2
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=First
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=End
|Rest|Dur:Half
|Bar
|TimeSig|Signature:4/4
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=First
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=End
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=First
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=End
|Rest|Dur:Half
|Bar
!NoteWorthyComposerClip-End
This is a conservative approach. Some scores use this approach, some do not.
