`tt connect` `\set output lua,block` not works

[d-enk]

> \set output lua,block
   ⨯ the command expects one of: lua, table, ttable, yaml

tt connect -x "lua,block" ...
   ⨯ unsupported output format: lua,block

but

tt connect -h | grep "set output"
  * \set output <format> - set output format (lua[,line|block] or yaml)

It looks like a wrong help message. The \help or ? in the console shows a valid help:

> ?

  To get help, see the Tarantool manual at https://tarantool.io/en/doc/

  This help is expanded with additional backslash commands
  because tt connect is using.

  Available backslash commands:

  \help, ?                        -- show this screen
  \set language <language>        -- set language lua (default) or sql

  \x[g,G]                         -- disables/enables pseudographics for table modes
