Narrative:
While on brush 1 arrival to stl, ZKC cleared us (air carrier flight xx) to cross brush intersection at or below FL180. When descending through FL210, the center controller cleared us to level off at FL200 and gave us a right turn (+/-30 degrees?). When level at FL200, we were at 72 DME stl (brush intersection = 68 DME). Had we continued descent rather than level off, we would have crossed brush intersection at FL180. We were then given further descent and handed over to stl approach control. Shortly thereafter, the controller informed us that the center had phoned and said we were subject to a 'possible pilot deviation.'

Title: WHILE IN DESCENT ON STAR WITH A CROSSING ALT RESTRICTION ATC INTERVENED AND ISSUED VECTOR CLRNC AND NEW ALT CLRNC TO REPORTER ACFT.
Narrative: WHILE ON BRUSH 1 ARR TO STL, ZKC CLRED US (ACR FLT XX) TO CROSS BRUSH INTXN AT OR BELOW FL180. WHEN DSNDING THROUGH FL210, THE CENTER CTLR CLRED US TO LEVEL OFF AT FL200 AND GAVE US A RIGHT TURN (+/-30 DEGS?). WHEN LEVEL AT FL200, WE WERE AT 72 DME STL (BRUSH INTXN = 68 DME). HAD WE CONTINUED DSCNT RATHER THAN LEVEL OFF, WE WOULD HAVE CROSSED BRUSH INTXN AT FL180. WE WERE THEN GIVEN FURTHER DSCNT AND HANDED OVER TO STL APCH CTL. SHORTLY THEREAFTER, THE CTLR INFORMED US THAT THE CENTER HAD PHONED AND SAID WE WERE SUBJECT TO A 'POSSIBLE PLTDEV.'
