This part isn't correct.

The default value of the
regexp will hide only the package whose name is at point, so just
pressing @key{RET} to the prompt will hide the current package.

It will hide every package whose name STARTS WITH the name of the
current package The default regexp is \`<name>; for the description to
be correct it should be \`<name>\'. In fact I think this would be a
better default, but it would be an incompatible change (but not very
serious). Given the wrong previous documentation, it might even have
been the original intention.
