Ah ok! Your question was about the test transaction. The thread title threw me off.

I was seeing tik toks and tweets saying the whale did no test transactions but if you look they kinda did because they moved the BCH first. This is worth a lot less so presumably they did it to make sure it was going to work before they moved the real bitcoin but I haven't seen anyone talking about it moving on BCH first

Can you explain your question a bit better? BCH and BTC are two separate blockchains, even if that address is from before the hard fork.
