Yes, basically the very same.
I (the user) try to do smtg, and the app do smtg other in the back.
And i (the user) get the impression that i did it right, what is not the truth.

I know that that is common (see IE which autom. add http:// in front of an URL, or how Win7 lies with UAC virtualizing)
but i did not want to see that more often.
