I can see the purpose. However, it still looks like overcomplication.
org-element-context takes care about this issue simply by narrowing to
current element (inline src block is an object and hence must end within
current element).

Makes sense.

Sounds like an omission in org-element-context. At least, the parser
could return :contents-begin and :contents-end. Then, you would also not
need to re-implement the parser.
