Does CallMolecularConsensusReads handle overlapping fragments?

[kcibul]

In the docs for CallMolecularConsensusReads it says:

Also, this tool calls each end of a pair independently, and does not jointly call bases that overlap within a pair

However later on in the usage there is a flag (true by default)

--consensus-call-overlapping-bases

What does this parameter enable (and how does that align with the statement in the docs?
