That depends on whether this person is motivated by a real desire to benefit you, or a desire to sound in a way that has maximum signaling value. (Note that the latter can be the case even when people honestly believe they're doing the former, unless they have a special and extraordinary degree of altruism towards you, which is typically the case only for close family and friends.)
