A simple reply to your question is Yes 2-3 articles from 1 domain have more weight than 1 article.

From my point of view, it is beneficial for Google as well as users also.  If a site gives you the link for more than one time then it will increase the authority of your pages.

Also, you can able to get links for more pages of your website and it's also good for getting more referral traffic.

and it is easy to get links from those who already linked to your pages instead of starting a cold outreach,

Hope it helps.
