Bond Percentages in Target Date Funds

The current spread in the percentage of bonds between Vanguard Target Retirement 2055 and 2065 is 1% (e.g., they have ~8% bonds and ~9% bonds, respectively). Will the difference in the percentage of bonds held be these two funds grow in the future, say at a certain milestone year, or will they always have a nearly identical mix between stocks and bonds? I’m asking as I currently own 2055, but I want to keep my bond percentage lower for longer, and I’m wondering if there is any value in keeping both years in my portfolio to split the difference in the level of bonds. With that said, if the difference will always be just 1%, then it wouldn’t seem worth it to allocate contributions to both funds. Thanks!
