I can't see the video, but perhaps they are trying to tap some of the "Autocad Inventor" crowd.
As for other ways to get that........It's all very well to use "configurations", but that feature is ONLY available on the top level GD product. The rest of us cannot get it.
And, having used SWX, I am not that impressed, with a certain exception oor two which drive me crazy in AD/GD
1) In SWX, if the constraint doesn't work, you hit undo and try again, all right there in the same window done in a second. AND IT UNDOES THE WHOLE OPERATION, including movements. In AD/GD, you close the window, mouse over, select the constraint, delete it, mouse up, undo, select constraints, mouse down, and resume work. Yes, the quick constraint has an undo function, but I find it less nice to use than the regular version. And straight "undo" may not do what you expect.
2) In SWX, constraints and parts addition do not seem to fling parts to the far reaches of the galaxy. In AD/GD, the parts come in appearing nearby, but actually may be metres away from where you think. And applying constraints may fling them even farther away. Some of that is inevitable, but it is annoying to need to find, and then collect the parts from way way off screen.
That said, I don't like a number of other things in SWX, so aside from being a recognized pro tool, which nobody can complain about if you use it, it isn't totally wonderful.
