This can be faked with invisible notes, but I realize that this may 
seem like
a "kludge".  BTW, you can use \hideNotes and \unHideNotes instead of
your own mkinvis / mkvis  (although you didn't actually use mkinvis in 
this
example).

Is that really standard?  I wasn't party to the original discussion 
about this, but I think
it looks better the way it is.  I'm certain you can tweak it to make it 
go up, though.

For others, this is what we're talking about:
\relative c' {
<b e g>2 ~ <b e g>4
}
Lily ties the b~b down, and the e~e and g~g going up.

Collisions are a problem, true.  You can avoid them with various tweaks;
see 4.3 Fixing overlapping notation and the Changing defaults chapter.

IIRC there was some discussion about that on the list a while ago.

You can force this with a \break or \newpage directly after the volta.  
LilyPond will
fiddle with the spacing of everything else so that your volta structure 
is the last thing
on the page.
