I thought most boxes would have an internal 50 ohm terminator so at first, 
I'm a bit surprised that it works.

If cables are short (which is not hard at 10 MHz), it would just be a 
resistive divider.  If the source impedance is low, it's just more work for 
the driver.  If the source includes 50 ohms, that's a 5:1 (1/6) divider so it 
probably works if the receivers are reasonably sensitive.
