Речь идет о defining relative clauses (они НЕ выделяются) и non-defining relative clauses (они выделяются). В первом случае придаточную часть (часть, в которой содержится дополнительная информация) убирать НЕЛЬЗЯ, так как это приведет к неясности предложения и/или нарушения смысла. В этом случае эта придаточная часть является ключевой уточняющей информацией. Во втором случае эту часть убрать можно, так как если мы ее уберем, смысл предложения не потеряется. В этом случае эта придаточная часть играет роль дополняющей, дополнительной, не совсем важной информации.
