That claim is false, unless perhaps you define a "32-bit Unix" as
"a Unix where sizeof(off_t) is 4".
The specific problem in scp is that the version of rcp that most of its
source code was copied from was very old and used a 32-bit printf format
to put the file size (which is sent as ASCII text) on the wire. This is
an implementation issue with the ylonen SCP and it's possible (in fact,
trivial) to write an scp which will interoperate but which does not lose
in this fashion.
