    Here is my solution in PHP

        $prows = count($P);
        $grows = count($G);
        $firstRow = array();
        $firstIndex = array();
        
        $result = 'NO';
        for ($i=0; $i <=$grows-($prows-1) ; $i++) { 
            $rowIndex = array();
            $offset = 0;
            while(($str = strpos($G[$i], $P[0],$offset))!== false)
            {
                $rowIndex[] = $str;
                $offset = $str+1;
    
            }
            $firstRow[$i] = $rowIndex;
        }
    
     
         foreach ($firstRow as $key => $value) {
             // code...
            if($result == 'YES')
            {
                break;
            }
            if($grows - ($key) >= $prows)
            {
                foreach ($value as $key1 => $value1) {
                     $keyIndex =  $value1;
                     $newKey = 0;
                     $lastIndex = $key+$prows-1;
                    
                          for ($i=$key+1; $i <($key+$prows) ; $i++) { 
                             
                          $newKey+=1;
                          
                          $str = strpos($G[$i], $P[$newKey],$value1);
                         
                    if ($str !== false && $str == $keyIndex) {
                            if($i == $lastIndex)
                             {
                               $result = 'YES';
                                break;
                             }
                    }
                   else
                   {
                    break;
                   }
    
                 
               }
               
                }
             
             
       
            }
            else
            {
                continue;
            }
         }    
     return $result;

    never says it should be exactly under... reputation management experts it states if the patterns is found in the string... it is found, they are not at the same indexes except IPTV, but I didn't found that requirement in the specifications.
