The line on the title?  It’s not really the language syntax.  It’s their way to tell you that ⎕R is an operator that receives required left and right operands A and B, and creates a ambivalent function that applies on right argument Y, with optional left argument X.

Right, though you can use this exact syntax on line 0 of a defined operator, e.g.

∇ R←{X} (A MyDefinedOperator B) Y

  R←A B Y
