fix: linter error in ambush

  * This commit fixes a linter error that somehow doesn't manifest
    unless some other, unrelated changes trigger it (see bpg#501 and
    bpg#505).

  * In addition it fixes a similar issue that had so far gone undetected
    by the linter.

  * Refactored the code in question into a function, since it was mostly
    duplicated.

  * Simplified a pair of conditionals that had the same code in both
    branches.
