No:
--8<---------------cut here---------------start------------->8---
-- Command: delete-region start end
This command deletes the text between positions START and END in
the current buffer, and returns ‘nil’. If point was inside the
deleted region, its value afterward is START. Otherwise, point
relocates with the surrounding text, as markers do.
--8<---------------cut here---------------end--------------->8---
