I have to admit I got a little confused reading that code (not that my
sed mess is significantly better, but at least I trust it because I
wrote it); but it looks to me like it's an abspath implementation on
the host filesystem (not the use of `pwd` in a few places).  That will
work for pruning in this case, since the problem case is already an
absolute path to a host directory.  But I don't see how it won't in
principle break things by expanding host paths.
