The behavior depends on many things: whether the invisible text is replaced
by ellipsis, whether the invisible property is front-sticky and/or
rear-sticky, whether the command made changes to the buffer, ...

My impression is that the text you quoted describes the behavior for
invisible+intangible text rather than just invisible.

Sounds much more reasonable.  If you want to be more precise, the only thing
that might be worth mentioning is the driving principle behind the code: try
to ensure that a subsequent self-insert-command will insert a visible char.
