why are these listed separately?

in my irssi config, i noticed that my ignores are listed separately like:
{ level = "JOINS PARTS QUITS"; channels = ( "#foo" ); },
{ level = "JOINS PARTS QUITTS"; channels = ( "#bar"); }

can I safely combine them like:
{ level = "JOINS PARTS QUITS"; channels = ( "#foo", "#bar"); }

?
