Baby carriers and hip development

My boy will be 4 months old 5/26. He is already quite developed for his age and loves to kick. I have a Baby K'Tan but it's so hit or miss with him. A lot if the time he gets upset because of all the fabric and he'll burrow his face in it. I have another more classic Infantino Carrier that he prefers. I noticed however in that one his legs hang down more and don't make the M shape that the K'Tan does. I know that shape is good for hip development.

My question is....

Is it ok for his legs to not make the M shape if he is already kicking a lot and quite active?
