FindRoot syntax?

I just defined an expression making use of FindRoot[] in the form

   g[x_,y_] := g /. FindRoot[ f[g, x, y]==0, {g, 0, 1} ]

where  f[g,x,y]  is a simple expression involving g, x, and y, and it 
seems to work just fine, churning out numerical values of g[x,y] for 
numerical inputs of x and y, with no obvious problems.

I keep feeling guilty, however, as if I've done something sinful -- 
specifically that I should be using a different symbol name or dummy 
variable in place of g on the right-hand side.

Is this syntax really OK?
