No, the default is still the same.  However, depending on the font you
are using, it could be that the a partial or even a whole 3rd line
will show, because when variable-size fonts are involved, it is hard
to compute in advance how many pixels to move for N lines.

Try in "emacs -nw", and I think you will see 2-line overlap.  If that
doesn't happen, either, perhaps there are local changes to your Emacs.
