We examine a recent proposal to show the presence of nonlocal Pancharatnamtype geometric phases in a quantum mechanical treatment of intensityinterferometry measurements upon inclusion of polarizing elements in the setup.It is shown that a completely classical statistical treatment of such effectsis adequate for practical purposes. Further we show that the phase angles thatappear in the correlations, while at first sight appearing to resemblePancharatnam phases in their mathematical structure, cannot actually beinterpreted in that manner. We also describe a simpler Mach-Zehnder type setupwhere similar effects can be observed without use of the paraxialapproximation.
