This legend is coming from early years of UNIX. First UNIX machines used swap partition to dump memory image to it in the panic. But core dumped starting from upper addresses. Then when you boot system after crash, swap starts filling up from lower addresses, and your dump is intact and you can work with it and move to filesystem. Modern unices dump directly to filesystem (those that can panic - linux AFAIK can't), so requirement to have swap size twice of memory size is not true anymore.
