Either way will work. What is happening is that when that RF amplifier
is suddenly turned on, the large dV/dT generates a huge voltage
secondary. The primary is closely coupled to that secondary and so
the huge transient appearing across the secondary will also appear
across the primary.
As I said is probably easier but shorting either winding should work.
Perhaps flip a coin :-) Heads its primary, tails secondary.
