I agree with those because they are past tense.
Where I disagree--and with no sense of authority--is on present tense:
Present indicative: If I am who you say I am (which I don't know because of amnesia) I'll turn myself in.
Present subjunctive: If I was who you say I am (which I am not) I would turn myself in.
Present subjunctive would be 'If I be who you say I am...'
Might sound weird but them's the breaks. Though I mostly hear people use a corrupt form, otherwise they'll stick a 'should' in there making 'If I should be who you say I am...'
'I were' is past subjunctive.

He is certain he would not vote for Hilary IF he was an American citizen.
Someone should invite him here so he can explain himself![]()
The confusion is likely because the Brits don't really use the subjunctive form anymore.
Educated people tend to, out of habit, but they are growing fewer, unfortunately.
