Tested by creating an application (package ID: com.example.testapp) that I signed with two different keys to produce TestApp.a.apk and TestApp.b.apk. Both APKs were VersionCode 1. I used the fdroidserver tools to create two separate FDroid repos TestRepoA and TestRepoB that each listed com.example.testapp with one APK (TestApp.a.apk or TestApp.b.apk based on the repo name).

Adding both repositories to FDroid in the order TestRepoA and then TestRepoB results in one listing in the FDroid client from TestRepoB installs TestApp.b.apk. If TestApp.a.apk is already installed FDroid prompts for it to be removed before installing TestApp.b.apk

Reversing the order of repository addition (adding TestRepoB then TestRepoA) results in one listing in the FDroid client from TestRepoA that installs TestApp.a.apk. If TestApp.b.apk is already installed FDroid prompts for it to be removed before installing TestApp.b.apk

This seems like a bug. I think the correct behavior is to have two listings for the same Version under the app details screen. Ideally with a means to distinguish which APK listing corresponds to which repository & app signature.

UI-wise the complete list of APKs should be in a different activity. Users should normally be able to trust the client enough to scroll past the text and any warnings and press install, without having to examine the full list of available versions. This allows all info from within and without the index to be displayed without being too cluttered and the list can be easily sorted. With a navigation drawer paradigm it wouldn't be too tedious to navigate.
