The "else" means the wrapped config bit applies to *all* workers and
processes of Squid except the one in the if-condition (process #4). It
is optional.
if ${process_number} = 4
# do something
endif
It does not even do anything in the code except invert a bitmask. An
"endif" then erases that bitmask. So an empty "else" is effectively
doing nothing at all.
Just like one would expect reading that config.
The bug is elsewhere (sorry for the pun).

Was that really the full config?
I dont see "workers 4" in there at all and something must have been
configured to use the shared memory TLS/SSL session cache.
