Aren't this two lines identical?

[Fedik]

nope, and that the issue, should be somehow fixed in J5, I guess

[Fedik]

Application class trigger diferent AfterRespond event for normal request, and for redirect (that usualy happen after POST)

[Fedik]

Here for respond

joomla-cms/libraries/src/Application/WebApplication.php

Lines 160 to 161 in c604191

	// Trigger the onBeforeRespond event.
	$this->triggerEvent('onBeforeRespond');

and there for redirect
https://github.com/joomla-framework/application/blob/e7b950d2d1358c0baac95a8633a60de20a1e82ab/src/AbstractWebApplication.php#L519-L521
