Thanks for your response. Maybe I'm missing something but I'm quite sure they are backwards in the program. I double checked in two SysML books. Also here's a link to a short SysML tutorial: http://www.omgsysml.org/SysML_Modelling_Language_explained-finance.pdf
A Block Definition Diagram is similar to a UML class diagram. It only defines the blocks and their properties (see pp5 in the reference). So it only needs to have block definitions, aggregation relationships, generalizations, etc . Which is exactly what the current Internal Block Diagram palate has.
An internal block diagram is a little more like an Activity Diagram where instances of the blocks defined in the Block Definition Diagram are shown along with the data flow between them through their ports.
Here's an excerpt from the "SysML Distilled" book about blocks: https://i.imgur.com/0EKPc1e.png

See Appendix A4 on page 594
If you have any references that counter my understanding, please let me know.
