The doc string now says

Set MAP as a temporary keymap taking precedence over other keymaps.
Normally, MAP is used only once, to look up the very next key.
However, if the optional argument KEEP-PRED is t, MAP stays
active if a key from MAP is used.  KEEP-PRED can also be a
function of no arguments: if it returns non-nil, then MAP stays
active.

which I think is clear enough.
