if GetLocalPlayer() == GetEnumPlayer() then

I don't really understand that well, I just want someone explains what it does really..
Here is full trigger to show their own multiboard to all players..

function InitCustomTriggers takes nothing returns nothing
    call InitTrig_ShowMultiboardforPlayer(  )

function Trig_ShowMultiboards_Func001A takes nothing returns nothing
if GetLocalPlayer() == GetEnumPlayer() then
    call MultiboardDisplayBJ( true, udg_PlayerMultiboard[GetConvertedPlayerId(GetEnumPlayer())] )
endif
endfunction

function Trig_ShowMultiboards_Actions takes nothing returns nothing
    call ForForce( GetPlayersByMapControl(MAP_CONTROL_USER), function Trig_ShowMultiboards_Func001A )
endfunction

function InitTrig_ShowMultiboardforPlayer takes nothing returns nothing
    set gg_trg_ShowMultiboardforPlayer = CreateTrigger(  )
    call TriggerAddAction( gg_trg_ShowMultiboardforPlayer, function Trig_ShowMultiboards_Actions )
endfunction

GetLocalPlayer() forces Warcraft III to run the action for only that player.

Well not always ^^.

if IsPlayerInForce(GetLocalPlayer(), bj_FORCE_ALL_PLAYERS) then

will always run.

GetLocalPlayer() returns the player that runs on the local computer, ie it will be different on each computer that is executing the script.

GetEnumPlayer() is just Picked Player.

I think you can make your script alot easier by just typing

call MultiboardDisplayBJ( true,udg_PlayerMultiboard[GetConvertedPlayerId(GetLocalPlayer())] )

Insteed of the ForForce line.

No... GetLocalPlayer() gets local player

I don't really understand that

Which part isn't clear for you?
Why is it executed for the local player only?
Or something else?

Why is it executed for the local player only?

That's the question.

That's the question.

It's simple.
Every function is executed locally (on each player's computer), so if a statement like

if (GetLocalPlayer() == whatever_you_want)

returns false, the code inside it won't be executed for the local player.
