A corporate jet crew and light twin pilot both asked jst approach about mutual traffic and were told to maintain visual but neither was advised of their converging tracks which resulted in the jet crew taking evasive action.

Narrative:
While on a shallow VMC descent into the lbe area; johnstown approach advised us of king air traffic at our 1-2 o'clock position. We advised 'traffic in sight' and the controller responded with 'maintain visual separation.' continuing our descent; the light twin also advised 'traffic in sight;' and again the controller responded with 'maintain visual separation on the jet.' while monitoring our TCAS display; I recognized the necessity to increase our rate of descent; but the system still barked an advisory command. It was evident that we were on a converging course; something not conveyed to us by the controller. Accepting the separation command; we essentially exonerated the controller of all responsibility. It would have been nice to know initially the degree of threat the light twin actually was. In the future I will not call traffic in sight descending into this area; relinquishing my protection. I'm surprised the controller did not advise the degree of threat posed by the twin.
