The \tweak command cannot be used inside a variable.

Well, the documentation tends to be maintained to a large amount by people not having written the underlying and likely underdocumented code. Often they make experiments, and when those experiments fail, generalize from the results.

Of course that is unfortunate because exactly when it is hard to get things right for obscure and/or technical reasons, the documentation is most necessary.

I think this is what originally happened with

Document Scheme replacement sample for \tweak.

Fix node name (it must not contain `.' followed by a space).

and that has survived and inspired code, in particular in connection with \flageolet, for years. In music expressions, you still need to do -\tweak so it's not like things have become a whole lot more consistent. One could actually let LilyPond complain with a more educational error message instead, but in this particular case silent acceptance seems not to do much harm. And my preferred end goal would be allowing just \tweak without preceding - everywhere but that's really tricky.

Should this rather be done in the LSR in the first place?
