As I wrote in the mail more checking should be done on freq ranges but 
as far as I have tested you get silly behavior but nothing dangerous.

In detail: let's say you write 8.100 in VFOa-3.5M, as the radio go from 
one vfo memory to the next using its index number changing band you'll 
have the sequence 1.8123 -> 8.100 -> 7.123.

I don't have the radio handy but I remember I also get the radio loop in 
changing vfo bands once I had the vfo-hf in between an out of range 
memory the next, to reproduce in the above example you add vfoa-hf = 
7.900 and radio (should) go 7.123 -> 8.100 -> 7.123 -> 7.900 -> 8.100 -> 
7.123 -> 7.900 in loop.
I suppose this is due to how the radio search when to go to VFOa-HF and 
where to next.

I all my test I never brick the radio.

I preferred to keep the freedom to put out of band values in those 
memories as this appear to be safe but we can discuss if it's better to 
add the range checking.

... your move ... ;)
