Yii 2 application on shared hosting server

Ok. So I need to transfer the vendor folder as well for the second yii2 application.

As I searched for reusing the vendor folder in yii2 application, I found the following article Moving the vendor directory for multiple projects | Wiki | Yii PHP Framework

Is it good to reuse the vendor folder or are there any potential drawbacks of doing so?

In order to not to utilize too much of the disk space, I was thinking to reuse the vendor folder of first application to second application.

What would be feasible here, whether should I reuse the vendor folder or upload it separately for the second application?
