It might happen something wrong with YouTube official documentation's demo feature in their page.

If you try the same request in Google API explorer, you'll get the items in the next/previous pages.

N.B I have face similar situations where in the YouTube's official documentation page does not work, but, by testing the same request in Google Data API, it works as expected.

My advice is, next time you face a similar situation, try in these places:

Test your request(s) in the YouTube official deocumentation page.
Test your request(s) in Google API Explorer.
Test your request(s) in your website, API, page, etcétera.

Example - page 1 of you request using the given channel_id UCxA5VFvNdlGUTingA9jMu3A.

URL: https://www.googleapis.com/youtube/v3/search?part=id%2C+snippet&channelId=UCxA5VFvNdlGUTingA9jMu3A&maxResults=50&fields=items(id%2Csnippet(channelId%2CchannelTitle%2Cdescription%2CpublishedAt%2Ctitle))%2Ckind%2CnextPageToken%2CpageInfo%2CprevPageToken%2CregionCode%2CtokenPagination&key={YOUR_API_KEY}
Page 1 - link demo in Google API Explorer.
