For example, at the time of the bitcoin cash fork I has 0.66BTC and converted my BCH to BTC so I got ~0.1BTC.
At the current fork, I had 1BTC and now hold 1bcg (which I'm still waiting on selling - though I don't think BCG has as much support behind it as BCC did).
Essentially yes. But we (as a community) don't tend to classify it that way as they become two separate currencies straight after the fork.
