Can exiting out of loop prematurely cause leaks in group enumeration?

[WorldMapper]

If the title didn't make sense, can the below snippet cause leaks?

private function BellerophonNB_DeathOrbCheck takes nothing returns nothing
        local unit enumUnit
        call GroupEnumUnitsInRect(ENUM_GROUP, WorldBounds.world, null)
        loop
            set enumUnit = FirstOfGroup(ENUM_GROUP)
            exitwhen enumUnit == null or GetUnitTypeId(enumUnit) == DEATH_ORB_UNIT_ID
            call GroupRemoveUnit(ENUM_GROUP, enumUnit)
        endloop
        
        if enumUnit == null then
            call ReleaseTimer(GetExpiredTimer())
        endif

        set enumUnit = null
endfunction

Assuming you only create ENUM_GROUP once, then it will not leak. Regardless, even if you did have to destroy a group, you should not be doing it inside the loop.

On a side note, if you are going to post JASS or vJASS code, just use [code=jass][/code] tags.
