The obvious difference I can see is the footnote numbers. In the Source file they are Arabic numerals and don't take much vertical space - in the Target file they are a different language (Hindi?) and take a lot more vertical space. This reduces the vertical space available for the 'page' contents in the Target file. There is a style associated with this number (Footnote Reference) which differs in its definition between the two documents.

I'm not seeing much difference in pagination apart from that. If you resolve that difference between the two files are you still seeing a pagination difference when pasting?
