selects the immediately following sibling. Same as
following-sibling::option[1], but the code was presumably written this way
so that 2 could be replaced by any number as the number of columns; if it
was 5 then the meaning would be "the first 4 following siblings".

"|" forms the union of two node sets: in this case, the union of "." (the
context node) and $others. So if you want four columns,
.|following-sibling::*[position() &lt; 4] selects this node and the next

not() takes the effective boolean value of its operand; the EBV of a
node-set is true except when the node-set is empty. So this (common)
construct tests true if $others is an empty node-set.
