Wikipedia API sometimes not returning redirects

Here's a Wikipedia URL:

When I navigate to it with my browser I get redirected to this URL:

But when I try to get the redirects for Ps4 using the Wikipedia API, it says that there are no redirects:

https://en.wikipedia.org/w/api.php?action=query&titles=Ps4&prop=redirects

{
    "batchcomplete": "",
    "query": {
        "pages": {
            "38596103": {
                "pageid": 38596103,
                "ns": 0,
                "title": "Ps4"
            }
        }
    }
}

I'm guessing that I've misunderstood the API somehow?

&prop=redirects returns all redirects to a page, see:

https://en.wikipedia.org/w/api.php?action=query&titles=PlayStation_4&prop=redirects

To do it the other way around you should add &redirects to your query:

https://en.wikipedia.org/w/api.php?action=query&titles=Ps4&redirects

Found the documentation at the documentation for query module:

Automatically resolve redirects in query+titles, query+pageids, and query+revids, and in pages returned by query+generator.

I'm not exactly sure why, but adding &redirects to the end of the URL seems to make it return the redirects property like I wanted:

https://en.wikipedia.org/w/api.php?action=query&titles=Ps4&prop=redirects&redirects

{
    "continue": {
        "rdcontinue": "38596106",
        "continue": "||"
    },
    "query": {
        "redirects": [
            {
                "from": "Ps4",
                "to": "PlayStation 4"
            }
        ],
        "pages": {
            "35723752": {
                "pageid": 35723752,
                "ns": 0,
                "title": "PlayStation 4",
                "redirects": [
                    {
                        "pageid": 5277874,
                        "ns": 0,
                        "title": "P s 4"
                    },
                ...
