impossible code in particleDistribution

by inspection - around line 140 of particleDistribution.C

    if
    (
        tagFieldName_ != "none"
     && cloudObr.foundObject<IOField<scalar>>(tagFieldName_)
    )
    {
        // Tag field present - generate distribution per tag
        const IOField<label>& tag =
            cloudObr.lookupObject<IOField<label>>(tagFieldName_);
...

It is either ignored by the if when the tagFieldName_ is actually a labelField, or runtime error if it was found as a scalarField, but followed by a lookup as a labelField.

Unless I missed something here.
