I’m oversimplifying here, but the news media generally uses terms like “government shutdown” or just “shutdown” to describe battles over proposed appropriations in the annual budget for the coming year and terms like “default” while talking about debt ceiling crises, which have to do with money that has already been appropriated/spent in previous budgets. The two year suspension is supposed to apply to the debt ceiling, which means that it should, in theory, stop potential default crises during that time, but that debt ceiling suspension is separate from negotiations over future appropriations, so it won’t necessarily stop a shutdown.
