Exactly!
But there are some uses of this feature:
1) To see what you did not buy (to dream a bit when you see a thread on FT with a 'gone' remark => you will be able to see that historic fare on screen

)
2) If you think to buy or not to buy now you are usually only concerned with inventory availability (booking class). However, there are some more things to consider: If fare sales restrictions say, for example, "TICKETS MUST BE ISSUED ON/BEFORE 15FEB11" then be sure to check the fare on 16FEB11 - in my case the fare DL T fare is not available after that date at all... Regardless of T inventory availability.
3) Sale fares and other fares to be changed: if you expect a sale or see sales restrictions as above - be sure to check the future date. The majority of sale and "updated USD level" fares are loaded long before the new first ticketing date.
