I have used vruby and other GUI frameworks only sparingly and years ago,
but they usually differentiate between creating a window and displaying
it on screen.

So I'd guess that closing (as in "I don't need this anymore") a window
might free system resources and leave you with a reference to something
invalid.

If you hde the window (as in "I might need it later") ruby keeps the
system resources around and the second use of b is fine.

Then again, I really don't know what I'm talking about :-)

Have fun,
