Correct, by rule it is a "catch." A "Catch"is defined by the manual as "A CATCH occurs when a BALL SCORED over the TRUSS by a ROBOT’S ALLIANCE partner is POSSESSED by that ROBOT before contacting the carpet, the ROBOT which SCORED the TRUSS, or HUMAN PLAYER."

A possession is defined by the manual as:
“carrying” (moving while supporting BALLS in or on the ROBOT or holding the BALL in or on the ROBOT),
“herding” (repeated pushing or bumping),
“launching” (impelling BALLS to a desired location or direction via a MECHANISM in motion relative to the ROBOT), or
“trapping” (overt isolation or holding one or more BALLS against a FIELD element or ROBOT in an attempt to shield them).

This is a clear example of a "launching catch." You should've been credited for the catch. Also it possible to do a "trapping catch" where a robot trusses the ball and the partner robot pins the ball against the guardrail or any other robot except the trusser. By rule the trussed robot cannot contact the trussed ball for the catch to count.
