I think we have a misunderstanding here. That page does not contain much
of technical details. Rather a history. AFAIU, initially Emacs wanted to
implement balanced tree structure to store overlays, but the effort
stalled for a long time. Then, a company rolled out a simple list
storage causing a lot of contradiction related to FSF and a mojor Emacs
fork. At the end, the initial effort using balanced tree on GNU Emacs
side did not go anywhere and GNU Emacs eventually copied a simple list
approach that is backfiring now, when Org buffers actually do contain a
large numbers of overlays.

I doubt that markers have anything to do with regexp search itself
(directly). They should only come into play when editing text in buffer,
where their performance is also O(N_markers).
Best,
