Haswell can either start verstage in a separate stage
right after the bootblock has run or it can start it
after romstage for compatibility reasons.
Haswell however uses a mrc.bin to initialize memory which
needs to be located at a fixed offset. Therefore even with
a separate verstage starting after the bootblock that same
binary is used meaning a jump is made from RW to the RO region
and back to the RW region after the binary is done.

On some systems, coreboot boots so fast that connected monitors
(mostly TVs) won't be able to wake up fast enough to talk to the
VBIOS. On those systems we need to wait for a bit before executing
the VBIOS.
