Yes, rather (this version is the 1st one that is modules only, but it still requires a MSI file to install).
Subsequent versions (starting with 6.5.1, which is not the same as 6.5 R1) are installed from PSGallery (with Install-Module).
It looks like the v13 option was introduced in 6.5.1, see also Re: PowerCLI - upgrade VM hardware from v10 to v13 failing
Btw, the current version is 10.2.0, and I would advise to go for the latest one.
