Do you by any chance use the +S[n] type modifier ? I would imagine
this to be the case in //depot/assets/... in particular. Those are
never lazy copied.

(//depot/files/branch1/ to //depot/files/branch2/ and //depot/assets/branch1/ //depot/files/branch2assets/)  The integrate command I'm running is "p4 integrate -o -v -Dt -t -b branch.name".  When the integrate was complete, drive free space on the depot drive dropped by tens of gigs, instead of the expected small amount due to overhead with lazy copies.
