I don't think so.
The "&& false" guarantees the code in the 'if' portion will never execute.
It's effectively commenting it out. I agree it was probably left over
'debug' code.
The "if( !isset( $_SESSION['PrevUrl'] ) )" has a very good chance of being
true. ANDing with boolean false NEVER has a chance of being true.
