Maturity matching buy and hold strategy

Can someone please explain what is maturity matching buy and hold strategy in context of active portfolio management of short term bonds …

Maturity matching is to buy the bond with a maturity that is the same as your intended holding period. For instance, you wish to invest in a bond for one year. So you buy a bond with one year remaining until it matures. (As opposed to buying a longer dated bond and selling it after a year, and before it matures.)

Got the point, thanks …
