He said "seeing if I could go without" medication, which I think is different than saying he's cured.

But your point about bipolar II is really important. Taking anti-depressants (SSRIs) when bipolar can induce rapid cycling--a speeding up and intensifying of the depressed-elated cycle, which can be very dangerous, as I learned the hard way after being misdiagnosed. Bipolar II is often treatable (I'm deeply grateful that mine is), but with different approaches and medications than depression.
