B737 FLC CLRNC QUESTION CAUSES MISINTERP OF APCH ISSUANCE OF SKEBR RNAV STAR INTO LAS.

Narrative

I WENT OFF FREQ TO TALK TO COMPANY ABOUT OUR GATE ASSIGNMENT. WHEN I RETURNED; LAS APCH HAD TOLD US TO DSND VIA THE SKEBR1 ARR; MAINTAIN 8000 FT. I WAS NOT ON FREQ TO HEAR THE CLRNC. MY FO EXPLAINED HE READ BACK DSND VIA THE SKEBR1 'EXCEPT' MAINTAIN 8000 FT. WE WERE BOTH UNDER THE IMPRESSION THAT APCH WANTED US TO DSND TO 8000 FT BECAUSE; WHEN THE FO MADE HIS READ BACK; NOTHING ELSE WAS MENTIONED BY APCH. APCH SHORTLY THEREAFTER TOLD US TO LEVEL AT 11000 FT AND EXPLAINED THAT DSNDING TO 8000 FT WASN'T WHAT HE WANTED. WE EXPLAINED THAT WE THOUGHT HE WANTED US DOWN AT 8000 FT BECAUSE WE READ BACK EXCEPT MAINTAIN 8000 FT; MEANING THAT HE DIDN'T WANT US TO DSND TO 7000 FT AT KIMME. I CALLED LAS APCH AND THE CTLR EXPLAINED WHAT THEY MEANT AND ALSO SAID THAT THEY WERE JUST COMPILING DATA AND THAT NO FURTHER ACTION WOULD BE TAKEN. THE VERBIAGE GIVEN BY APCH FOR SOME REASON IS VERY MISLEADING. I DON'T KNOW IF IT'S JUST THAT I (AND OTHERS) ARE CONFUSING THIS PROC AND IT'S DIFFERENT VERBIAGE WITH THAT OF THE ARRS INTO LAX WHICH SEEM TO WORK QUITE WELL WITH NO CONFUSION. I ABSOLUTELY BELIEVE; IT'S THIS VERBIAGE THAT IS CAUSING THE CONFUSION. APCH COULD PERHAPS WAIT UNTIL AFTER POVOC (AT 9000 FT) TO GIVE THE 'DSND TO 8000 FT' CLRNC AND THIS PERHAPS WOULD PREVENT FUTURE MISUNDERSTANDINGS.
