請問以下四句是否只是表達方式不同而意思一樣？

1/「No goods or waste shall be placed or disposed of outside unit A of the premises at all times except in the specified area.」

2/「No goods or waste shall be placed or disposed of on the premises outside unit A at any time except in the specified area.」

3/「No goods or waste must be placed or disposed of outside unit A of the premises except in the specified area at all times.」

4/「There shall be no goods or waste placed or disposed of within the premises outside unit A except in the specified area at any time.」
