I think the answer is no. There are explicit checks in Read code path to ignore

I believe (have not tested) that you would still see the range ghosts talked
about here http://wiki.apache.org/cassandra/FAQ#range_ghosts until compaction
had removed all the columns, and the row once all the columns are gone. Expired
columns are purged during compaction when their ttl runs out.
