There's no way to tell if that's 'PBI' or not. I don't see anything about it that is necessarily wrong. For future reference, unidentified varieties of Sempervivum will remain forever and always unidentified. There are too many similar varieties and they grow so differently in different settings that identification is futile.
Generally, but not always, responsible vendors send the right variety. Simply Succulents is reasonably responsible, but they all fail sometimes and even they have the problem of receiving incorrectly named stock and unknowingly passing it on. None of us are immune.
