The init and plugins_loaded hooks are already run before a plugin is activated. That’s why your first code doesn’t work but the second does.

If I had to guess? The plugin activation hook is firing before the rewrite_rules_array filter is applied, resulting in the rules being flushed before you make changes to them. See here for the Codex-recommended implementation, using the wp_loaded action hook.
