Consider :
1. Monday : You do a first clone to the Standby without the TEMPFILE
2. Tuesday through Thursday: Your Standby in MOUNT state is
always "rolling forward"
through ArchiveLogs shipped from the Primary
3. Friday morning : Your Primary goes DOWN. No access to the
Primary Storage at all.
4. Friday afternoon: You OPEN the Standby.
Hmm. .. we don't have the TEMPFILE .
Let's add the TEMPFILE.
5. Friday evening : Users are happy, transactions continue..
When would you have been able to copy the TEMPFILE ?
A Standby HAS to assume that the TEMPFILE is not available.

I think you mean the first cloning process of standby set up.
You do not need to copy the temp files.
And if this is a physical standby you do not need them until you
open the database as primary or read only
They are only needed when you open the database not in mount stay
which is the default state of the database during log apply.
