Not fully correct, the backticks are context sensitive, in scalar context `ls -l` will return a concat of all lines. (a list array¹ in scalar context returns the number of lines)

backtick/qx in perlop

In scalar context, it comes back as a single (potentially multi- line) string, or undef if the command failed. In list context, returns a list of lines (however you’ve defined lines with $/ or $INPUT_RECORD_SEPARATOR), or an empty list if the command failed.

¹) corrected, thanks to no_slogan. It very much depends on what the command within backticks returns.
