Yes, I'm aware about this feature. It doesn't help.

I think this possibility can be excluded because of:

1) I have performed 'guix pull' on the system B for the last few
months (maybe half a year) a few dozens of times and every time I
observed it build all the derivations by itself.

2) I had performed the experiment. I queried [1] for the latest
commit with substitutes and performed 'guix pull --commit="obtained commit"'
on systems A and B (they are both x86_64). The results of this experiment
are  presented in my first message.

3) Today I have preformed the similar experiment. According to [1] the
latest commit with substitutes was "5a624adfd". Again, the system B
have built all the derivations by itself while the system A have
downloaded substitutes.
