Look in the SIMPLE COMMAND EXPANSION section of the man page:
If there is a command name left after expansion, execution proceeds as
described below. Otherwise, the command exits. If one of the expan-
sions contained a command substitution, the exit status of the command
is the exit status of the last command substitution performed. If
there were no command substitutions, the command exits with a status of
zero.
It's the final paragraph.
