Because with such settings (to workaround the fake buggy TCP session seen in
the capture) any error/restransmission TCP packet is forwarded to upper layers
(which might lead to duplicate packets see in the protocol running on top of
TCP) and no TCP concatenation is allowed (in case some upper layer packets are
spanned over several TCP segments).
Those options are on by default to get the best decoding experience out of the
box. They can be changed in case of very specific needs (like in this case).
