I think you should be fine. It would have been better to cover the seeds, but the water will do that for you too. Mother Nature doesn't till the ground to spread seeds, so your method is just more natural then mine. LOL
The only other consideration is if your soil will grow Bermuda. Since it grew Rye, I would think it will grow Bermuda. You can always do a soil analysis to find out for sure what the soil needs and work on improving it. Mine was pretty bad since I had removed all the top soil and dug down several feet over the entire area. I wanted to field to catch and divert water to my pond!!!!
If you're curious, I have a thread going on it over at Tractor By Net.
