To add to Kontact's post - position rules. If the post you have allows setting your seat in that position, it works. (Well, if you have the seat completely slammed and the rails are titanium or perhaps CF and the start of the bend is in the clamp and that clamp has sharp edges, the rails may break.)

That said, I try hard to get seatposts where the clamp sits roughly centered on the rails. Best for rail long life though that usually doesn't matter, probably best for suspension and shock absorption for your butt and my real reason - it allows any and all tweaking to the most critical fit adjustment on the bike. People pay hundreds for their bike fitting sessions. A very expensive seatpost of that centered setback might cost a single hundred dollars and be a continuing fit blessing the next decade or two.

That said, I paid far more for two custom made seatpost of 160mm setback for my two titanium customs - because I had those bikes made with 74 and 75 degree seatposts - to allow very short chainstays, decently large tires and fender. (My butt wants a normal 20mm setback post on a 72.5 tube.) Posts were made by Ti Cycles with Thompson clamps and titanium tubes. Thompson so a joy to work with. Total keepers and that clamp allows me probably 2 cm adjust in each direction. (But if I were smart, I would have asked about bending the seat tube and using a normal post! Next life!)

I've known about the short chainstay, steep seat tube and therefore big setback needed for my best fit since I raced nearly 50 years ago. Slammed seats were my norm. Broke my first ti railed seat. (I'm light. My butt really likes ti rails on those steep angled bikes.) Rode the compromise of not enough slam for fit to keep the rails intact on several bikes. Then started paying for good big setback posts. Yeah!! (Customs, the lugged steel Nitto and the SR 100 something adjustable MTB posts. Those SRs will be old but probably not expensive. Max setback is huge. The steel Nitto has a lot of setback, is beautiful, really nice to work with and much lighter than it looks. Visually an upgrade to any bike you put it on.)
