This sounds like it would be concerning for individuals on a work status (TN, H-1b, etc) who are explicitly not supposed to perform work outside of their job or specialization. There's some grey area here for sure, but this seems pretty clearly outside the scope of authorized work.
An engineer helping with a support ticket once in a while, sure, I think it's a reasonable expectation, but I can't see how explicitly putting this as a job responsibility isn't going to muddy the waters for some people.
