Yes, really.  The very instructions you used as example put their
results in the flags register.

That's just because SSA doesn't deal with two assignments from the same
operation.  The C code is innocent.

In concrete machine terms, both use a label; or actually, a hardware
address.  The machine code doesn't use labels.
