Well, you are right about that, but this is the kind of thing I usually see done in things like job descriptions to avoid gendered third person and to sound more personal
"Sie können fließend Englisch sprechen und [...]"
Using "sie" to specify one person in german sounds a lot like "pluralis majestatis" to me. Which is sorta like (but not quite) the "royal we" in english

no. we have that too, but it's the second person plural. Nobody uses this any more though because we killed our kings back in the early to mid 1800s :p
The only "Sie" in use is the second person singular in formal form (something else English doesn't have) when used to address a person directly.
