A backlist title stops behaving like one thing once you sell it direct.
In a shop, it has to justify its shelf space as a clean, ordinary product. On an author site, the same book can be part of a bundle, carry a bonus chapter, sit at a different price point, or do a slightly different job altogether. That changes the practical shape of the list quite a bit. Not just how you market it, but how you package it, describe it, and decide what belongs with it.
The awkward bit is that the book still has to make sense in both places.

The danger is pretending the same description can do both jobs. A shop listing and a direct-sale page are not the same beast, even when they point to the same book. One needs to be legible in a crowded catalogue. The other can afford to be a bit more specific, even slightly odd. If the copy doesn’t change, the book ends up doing all the adaptation work itself.
