meaning - Does the term "avoid" leave room for exceptions?

@David's interpretation is somewhat unconventional, but I must agree with him. Unless an action is explicitly forbidden, without exception, it is reasonable to assume that certain exceptions may apply in extenuating circumstances.

Take, for example, the 10 Commandments, one of which is "Thou Shalt not Kill". Yet, the same lawgiver specifically authorizes, even commands killing in certain circumstances.

This is why in English we say, "Never say never".
