Multiple entires with the vignette

I am not sure I will be able to pick my BRP the first time I enter the UK. My decision letter says that I can enter multiple times but there will be additional security checks if I enter more than once without the BRP. The vignette itself says it’s valid for multiple entries. But this page on says that a new vignette is needed if you do not get your BRP the first time you enter the UK.

So can I enter multiple times without picking up my BRP?
