DO NOT TAKE YOUR HAND OFF THE TILLER. Heading up in a gust depowers the
sail. (And gains distance to windward when beating.)

Reducing sail makes life easier, but if you have the sheet free and are
ready to head up with a quick twitch of the tiller, you can unload
instantly. Hiking out is good for boat speed, but not required to avoid a
capsize.

by "heading up" he means pushing the tiller away from you as if you were
tacking.

A manoeuvre also known as "luffing".
