First, kindly don't use Page Views and Exits against eVar10 and eVar32. They are conversion metrics and they are to be used only against the events. So Page Views and Exits will not match for eVar10 and eVar32.
Second, I can see that you are storing eVar10 and eVar32 values in prop10 and prop32. Map Page Views and Exits against the variables prop10 and prop32 to compare, it should definitely be the same.
Only scenario i can imagine is that if you use prop10 in s.tl() call but not prop32 and if the person exit the page after the s.tl() call, Exits will be attributed to prop10 but not prop32. There wont be any Page Views for both and thus Page Views metrics will not have any clash.
