It doesn't make any difference. Do a mem/c with HIMEM.SYS first, then one with DOS= first, the result is exactly the same.

DOS=HIGH,UMB isn't something that is being loaded into high memory. It's a switch - a text instruction that the DOS loader reads in order to know how it should map memory. Which line it's on in the file doesn't alter its action, it only has to be there to be read.
