Why in this tutorial (Test program 2 - page 14) is:

MOV A,SBUF
MOV SBUF,A

???
I think mov SBUF,SBUF should works , am I right?


Formally, yes.

However, you might be opening a Pandora's box using it. You might "awake" a bug using something which the manufacturer did not expect to be used... They sometimes have problems implementing functionality which is almost taken as granted at a product as mature as the '51s are - see the AT89C8253 and it's earlier revisions' erratas...
