Well, you did delete something, no? There are rows that aren't in the
output that would have been there if not for the filter condition.
And, btw, one person thinking it's clear doesn't make it so. There
are actually three numbers that could be involved here: the number of
rows arriving at the filter, the number passed by it, and the number
rejected by it. I think that "nfiltered" could possibly mean any of
those three. A non-native speaker of English would be even less
likely to be sure of what was meant.
