Backcourt?

[Grail]

Had a situation last weekend.

A1 dribbling the ball toward the frontcourt. Right foot crosses into front court, dribbles ball in front court, left foot comes to rest on the mid-court line. Left foot has toes in front court and heel in back court.

A picks up his dribble and pivots on the left foot (still on the line) and places his right foot in the backcourt.

I let the play continue. Should I have called back court?
