Erik, it sorta depends on what you are looking for. Your construct search is looking for two VERB infinitives within the same verse, which can easily be done in the search box:
[VERB infinitive] <FOLLOWED BY> [VERB infinitive]
Now, if you want them to agree on a variety of things (lemma, inflected form, root, etc.), you'll have to use a construct, as the AGREE bubble practically only exists within the construct. This would look like this:
Finally, your search [COUNT >1}@[VERB infinitive] is actually pretty close. You can do [COUNT 2-100000]@[VERB infinitive] to find infinitive Verbs that occur more than once within your search range. But, this also might not be what you are looking for. My guess is what you want is the construct AGREE search, which due to its nature, can only really be built in the construct.
Edit: Fixed search logic, as [VERB] <AND> [VERB] will also find hits that only have 1 VERB.
