My question should be regarded in the category of quick concept modeling. I think I understand why it acts like that, but should there be also another quicker way?
On the screenshot, you can see a simple box with two filleted edges which produce creases. Creases prevent me from successfully move one edge.
In the video, you can see Rhino behavior when using gumball (which is usually great). But how one can make such modification to the shape on the fly?
To achieve this very simple effect I used ExtractSrf , modified top surface and then used Sweep2 commands to fill the gaps and Join to join everything. Which is a really long path if I would change my mind and want to modify angle or filet again.

Even after I tried something different and removed surface with the fillets and replaced it with one made with Sweep2 command, so there are no creases, it still produces strange results.
(I am not a modeling pro, so I ask)
