Your program would still be in memory with an \>OLD command.
As long as it was a basic prog, the machine code loaded *RUN was lost and had to be reloaded from tape, yes.
A pain for games but I don’t really recall accidentally pressing the break key much it was out of the way up right.

But any data was lost and I saw break get pressed accidentally fairly often at school and amongst friends.
