a if statement with a true logic value then followed by a false value

Can anybody help me understand the following function?

looks the firstRun was assigned a logical TRUE value to it at the beginning of function. then why in the if(firstRun) function, a FALSE was assigned to firstRun again? what does that FALSE do?

RunIterativeStrategy <- function(mktdata){    
    firstRun <- TRUE    
  for(a in 1:3) {    
    for(b in 1:3) {    
      runResult <- TradingStrategy(mktdata,a,b)    
      if(firstRun){    
        firstRun <- FALSE    
        results <- runResult    
      } else {    
        results <- cbind(results,runResult)    
      }    
    }     
  }    
  return(results)
}

many thanks
