It will work, but it will set the mode on each user seperatly, that means if there are 50 people, it'll set the mode 50 times, which isn't a good idea.
That solution should only be used if it's on a very small amount of people, and even then, i'd go with setting multiple nicks in 1 mode.
The reason it'll work btw, is because of the $* identifier. It's undocumented in the help file, but is mentioned in the
versions.txtBasically it's calling the command /mode for each nick selected, so if you select 20 people and use that code, /mode will be called 20 times.
As an example of how $* works:
1. //tokenize 32 one two three four | echo -a $*
2.
alias blabla inc %x | echo -a %x - $1-
//tokenize 32 one two three four | blabla $*
