Over at Uncommon Descent, it is asserted that Michael Behe says that Intelligent Design is falsifiable, because if someone can show MB a bacterium evolving a flagellum he would reject ID. If MB actually said that, then MB does not understand falsificationism.

Either Behe or the author of that article (or both) has a clear misunderstanding of falsificationism.
