Good to know, but yes, this is expected. Spectre is a hardware level vulnerability and is still exploitable in-process. The OS level patches likely reduce the impact of Spectre by making it harder to exfiltrate data over certain security boundaries such as the kernel (through a lot of retpolining), but they do not (yet) seem to contain any microcode patches that would in any way change the caching or out of order execution behavior of the CPU.
