To be expected. None of this is at all bizarre, it's all quite normal... honest.
Always make damn sure the third terminal is isolated and is not in fact an earth terminal connected to a metalic liner in the plastic baynet holder body. I have both types in my spares box. I even found one case of a 3-terminal baynet lampholder where the third terminal was labelled "loop" in the plastic molding, but was connected to the metalic liner.
Ooh - I've never come across a battenholder where the third terminal was other than for loop-in. Usually there's a separate earth terminal in the pattress/base. Thanks for that warning.
