dns settings questions

I have a profile hosted by a social media site that I would like to customize with a personal domain. The directions involve me changing my domain's A record to a certain IP, but my IT guy says that doing so will screw up the other domains that are hosted in my family's all-inclusive account. Why?

I have a profile made on a special website and now that I have a premium account, I can use a custom domain with said profile so that www.myname.com points to my profile, etc, etc. The directions for accomplishing this task are as follows:
1. You have changed the domain's A record (IP) to [special IP]
2. You have entered "@" or your domain name in the Host column of your DNS settings
3. All old A records are removed
4. No other redirects are in place
5. You have entered the URL of your custom domain correctly on your Settings page
6. You have waited 72 hours for the change to occur across all servers
When I brought these instructions to a relative to help me since he is the person in charge of my domain, he informed me that because my custom domain (myname.com) is hosted along with other domains owned by our family, changing the DNS for myname.com could irreparably damage the other domains. He offered me a workaround of simply pointing my domain to my profile using a stealth redirect, but that has caused a problem with the way my website appears on mobile devices. I would like to know more about this process so I can have a more productive dialogue with my relative.
If there are other domains hosted on an account along with myname.com, will it really be that dangerous to change the A record of myname.com? Why?
FWIW, the other domains are completely separate, individual sites and are not subdomains of myname.com.
