A transformer should always have its
- primary shorted or off load.
- secondary shorted or on load.
- secondary open circuit or on load.
Explanation from PART66Online
A voltage transformer's secondary may be safely left open-circuit (no load) or connected to a load, but it must never be short-circuited, which would draw excessive current. Likewise the primary should not be shorted. Thus the safe states are secondary open-circuit or on load.

Shouldn't it be secondary shorted or on load?

If you short out the secondary winding, the primary will burn out.

May be confusing it with an autotransformer.
