Hi, @EV-2.
The Alt Host designation allows YOU to start the meeting from YOUR account. It's one of the security feature "privileges" that helps avoid people having to share each others' login info.
This Zoom Support article discusses setting up an Alt Host, including the prerequisites:
https://support.zoom.us/hc/en-us/articles/208220166-Designating-an-alternative-host
But it also has this important tidbit of info:
- The alternative host can start the meeting using the join link in the email or calendar invite sent to them by the host. The meeting will not display in the upcoming meetings list in the desktop client, mobile app, or web page for alternative hosts.
So the meeting doesn't show up in your Zoom desktop client - or really anywhere else, for that matter, other than in the Join link which the Host should send you.
And you can start the meeting from any device where you could normally start a meeting... which is pretty much anywhere!
If you are being designated the Alt Host for a specific person a lot, you and your frequent host-mate should consider the Scheduling Privilege as an even easier way for the two of you to co-schedule meetings. To me the great advantage of this is that the meetings show up in both people's Zoom clients. See this Zoom Support article for more info:

Some of the Zoom articles can be a little technical. Don't be afraid to pop back here in the Zoom Community with any questions!
