Thanks author very much for solute my problem.
Now I found same pattern of the same buffer was different with two window.
For example
The keyword 'formDataEditor' was highligh in two window. but the color was different.
For Hi/Find formDataEditor multiple files, the color was same, but why Hi/Set word color was different for two window?
Thanks for your update. Each window can have different highlighting patterns by default, and you can use Sync Mode and the configurable option :h HiSyncMode.

Maybe I need some config to keep color same?
