I wondered what google translate would make of a dead language so I tried those phrases. Neither of them seem even close, so (as I don't speak Latin) I don't know whether the issue lies in google translate, the complexity of what's being portrayed, whether the phrases are too idiomatic, or whether these idioms would require context around them to translate correctly.
"nimium valedīxit": He got too sick
"totiēns valedīxit": He was always well
Edit: Playing around with google translate, "nim valedīxit" translates to He said goodbye. But "valedīxit" translates to Said goodbye. "Nimium" translates to Too many
So somewhere in that complexity it does seem to be that those two words have a meaning that build off eachother for their meaning, but google is considering it literally
If anyone has an explanation for these phrases rather than my guess work, I'd love to hear them!
