Practically, it means nothing of course.
- the product owner sets the backlog priority
- team estimates
- team commits to what it can deliver from the backlog

Rinse/repeat
There’s no shaming part
Edit: format
Unless a person has no shame, failing a commitment I certainly believe is intrinsically shameful. Some cultures would commit seppuku if you don't deliver on a commitment.
The words, "you failed on your commitments" seems very much like shaming. Thus the move to "forecast" over "commitment"

*edit (addendum): Invoking 'seppuku' might be a bit sensationalist, my apologies. The southerner in me is coming out - saying someone does not live up to their word is a very big deal.
