The edit tab is swapped server-side by VisualEditor in PHP. The JS code is only used to fix it up for cached unedited articles (upto 30 days) following a configuration change such as enabling in a namespace, or enabling by default.
That use case was considered and we figured that'd be okay given it's not common in production in general. And when it happens it automatically drops off following cache roll over.
When I wrote it, there was no flash. The js code and PHP code were functionally equivalent. The JS code is a no-op – unless the wiki's configuration changed recently (namespace, VE default etc.) and the user is anonymous and they're viewing a not-recently-changed cached page.
