Narrative:

Cleared to land on bos runway 27. At approximately 2-3 mi from runway, were advised by controller that traffic was departing on the 'crossing runway.' we saw traffic rolling on runway 22R, and thought that was the traffic he was referring to. On short final, the controller said 'air carrier X.' a few seconds later, as we were in the landing flare, we saw an air carrier Y flight just lifting off runway 15R. Just prior to the intersection of runway 27 and runway 15R, at that same moment, the controller said 'air carrier X, go around.' I very quickly decided that was not a good move, and just said 'no' to my copilot, who relayed a 'negative' on the frequency. The controller then said 'ok, cleared to land.' after arriving at the gate, I called the tower and talked to mr X, the supervisor. He said he had no problem with the flight crew actions in this event, and was glad I did not do the rejected landing. He said this was a controller error. I suggested to him that the tower should not be using different frequencys for operations on crossing runways. Supplemental information from acn 509805: each aircraft was on a different tower frequency, so we didn't hear the other aircraft cleared for takeoff. This contributed to our not seeing the other aircraft until the last moment.

Title: BOS TWR ADVISES LNDG B738 TO GO AROUND AS B732 DEPARTS FROM INTERSECTING RWY. LNDG ACFT REFUSES CLRNC.

Narrative: CLRED TO LAND ON BOS RWY 27. AT APPROX 2-3 MI FROM RWY, WERE ADVISED BY CTLR THAT TFC WAS DEPARTING ON THE 'XING RWY.' WE SAW TFC ROLLING ON RWY 22R, AND THOUGHT THAT WAS THE TFC HE WAS REFERRING TO. ON SHORT FINAL, THE CTLR SAID 'ACR X.' A FEW SECONDS LATER, AS WE WERE IN THE LNDG FLARE, WE SAW AN ACR Y FLT JUST LIFTING OFF RWY 15R. JUST PRIOR TO THE INTXN OF RWY 27 AND RWY 15R, AT THAT SAME MOMENT, THE CTLR SAID 'ACR X, GO AROUND.' I VERY QUICKLY DECIDED THAT WAS NOT A GOOD MOVE, AND JUST SAID 'NO' TO MY COPLT, WHO RELAYED A 'NEGATIVE' ON THE FREQ. THE CTLR THEN SAID 'OK, CLRED TO LAND.' AFTER ARRIVING AT THE GATE, I CALLED THE TWR AND TALKED TO MR X, THE SUPVR. HE SAID HE HAD NO PROB WITH THE FLC ACTIONS IN THIS EVENT, AND WAS GLAD I DID NOT DO THE REJECTED LNDG. HE SAID THIS WAS A CTLR ERROR. I SUGGESTED TO HIM THAT THE TWR SHOULD NOT BE USING DIFFERENT FREQS FOR OPS ON XING RWYS. SUPPLEMENTAL INFO FROM ACN 509805: EACH ACFT WAS ON A DIFFERENT TWR FREQ, SO WE DIDN'T HEAR THE OTHER ACFT CLRED FOR TKOF. THIS CONTRIBUTED TO OUR NOT SEEING THE OTHER ACFT UNTIL THE LAST MOMENT.
