Received PDC via CPDLC with a FMC load prompt for a reroute. Wasn't clear what the change was; but the beginning said direct SYRAH; which is on the TRUKN2 SID.  We loaded the change and that removed TYDYE; TRUKN and COSMC. Unsure this was what ATC intended; we called Clearance to verify.  ATC said no we were to fly the TRUKN 2 as published.They mentioned other 777 and 787 flying direct SYRAH on this departure. Something is wrong with the datalink PDC.
B787 F/O reported the PDC reroute they received via CPDLC was in error.
