True, if /this isn't just a mount point for //this, meaning
that the "that"s are two different files.

Apart from the urge to question the sanity of anybody
setting something up like that, I see that this is a serious
objection to consider.

I mean, seriously, something like that *is* prone to typos,
and whoever does that will end up manipulating/using the
wrong file rather often anyway.

Which leads to the point that such a setup makes injecting
not mounted network shares like that quite dangerous...

Just my thoughts... Doesn't matter anymore anyway, as my main
question of interest was answered. ;-)
