The 2nd step does more than bell the mouth, it also expands the case.

Well, If I had ever taken my dies apart, I would've known that! I stand corrected.

...has something to do with the "grip" of virgin brass... This problem never happens once cases have been fired and tumbled.
That's correct. Factory new brass is very grippie. Sizing & expanding is noticeably harder on them. However, it shouldn't be pulling the brass out of the shelf holder.
It may be a combination the slight smaller case rims & the shell holder's (larger) size? You could always try a new/different brand shell holder to see if it helps.
