Yes, that’s precisely what I meant with “usually”: a sufficient amount of systems keeps sufficient amounts of memory alive to make this feature worth being in existence, even if counter-examples exist and no spec supports this usage.
The reset button as the only way out of a crash is such a PC thing though. Some machines have watchdogs, and some have something like ddb(4) on BSD or SysRq on Linux that allow for warm reboots even in the face of a crash.
