You forgot that the rest of the world uses 8 character tabs instead
of four.. ASCII art repaired above compliments of "expand -4" :-)

This is a known issue.. from "man libalias":
BUGS
PPTP aliasing does not work when more than one internal client connects
to the same external server at the same time, because PPTP requires a
single TCP control connection to be established between any two IP ad-
dresses.
Fixing it would require a non-trivial amount of work in libalias.
