Commercial License Sync and Personal Sync on same account

I am looking at purchasing a commercial licenses for my company. However I use a personal sync tied to a personal email on my personal computer (which is also used for work)

I would like to use my business email for the commercial license so there minimal/no cross pollination between personal and work. Obsidian is used on the same computer.

Looking at sync setup for vault there’s no place to add an account. Am I able to associate sync with my business email and also associate a separate sync with my personal email?

Looking at the settings in obsidian, it seems the license key would tie to the account of my app, which in this case is my personal account. Is there a way to separate these?

Additionally, If I want to purchase a license for an employee. if they were removed from the company, they would be removed from the share(s) however, this employee could continue using this sync account under the business email?
They can continue using the app afterwards as their own personal obsidian, but the license would still be a valid license under the companies domain.

Is this all correct? Is there a way around this?
