ZZZ1 X sector called ZZZ X sector; which owns 33000 and above and asked them to descend both aircraft to 31000 feet. ZZZ1 never pointed out the aircraft to me at the ZZZ Y sector. Upon calling ZZZ1 and asking the controller he responded with 'that's not my job; I told the ZZZ X sector to descend him; so that's their coordination.' I told him that I believe he was incorrect and that he should look up the procedure. This is a safety event because we often have traffic at 32000 feet; luckily at this moment we did not; but ZZZ1 X sector has been misinformed on coordination procedures.ZZZ1 X sector needs to know that when they have another sector issue control instructions; they are in fact responsible for any additional coordination that that aircraft may need with surrounding sectors. I feel that if the controller that did this does not hear he was in fact wrong; he will surely have a safety event involving a loss of separation. Luckily; these two aircraft in this situation were two separate airspace violations; so we did not have a loss of separation involving two aircraft.
ATC Center Controller reported improper coordination by an adjacent Center Controller; due to an apparent misunderstanding of standard procedures.
