Sort of, but I think it will only delete Lojban words, at least if
its grammar really is:

text = su-null (rest of grammar)
su-null = SU / any-word su-null

But I don't really know if that is its grammar, it is not explicited
anywhere.

In any case, the way I understand SU, the parser will process
everything and only when it gets to a valid SU erase everything.
A true "beginning-of-parsable-input" could not be quoted for
example ({zo su} would be impossible), in the same way that
{fa'o bu} is impossible, because no processing would occur outside
of those markers.
