The following documentation comment has been logged on the website:

"The @@ operator also supports text input, allowing explicit conversion of a
text string to tsvector or tsquery to be skipped in simple cases."I believe
that the text is saying implicit, but uses the word "explicit" instead. Is
this a typo? Thanks.

I think it's intended. The point is that instead of, say,
tsvector_column @@ 'query here'::tsquery
you could just write
tsvector_column @@ 'query here'

Right. You can skip the explicit conversion of adding a type cast.
