No it isn't. It's checking if the element exists and is non-empty.

a:propstat/a:prop[office:EndDate = office:StartDate]

selects all those a:prop elements that have endDate = startDate (they
must both be present, and equal to each other).

But perhaps the EndDate and StartDate are children of different a:prop
elements that are children of the same a:propstat? 

In that case you want:

a:propstat[a:prop/office:EndDate = a:prop/office:StartDate]
