<upd_detl>Clone of xref, + "to be on the same page". 

I think these are roughly synonymous. Other form is more common.

Not clear to me yet if the difference between を and が implies different formulations:
"to be in step with" "to be keeping pace with" "to be moving in lockstep" "to be in alignment with" (and in the other direction, "to get on the same page")

I won't try to solve this one.

足並みが揃う has an entry has an entry in jmdict as negation(which is where I started), and which I am going to go vote to delete.</upd_detl>

足並みが揃う〔足並みを揃える〕
あしなみがそろう／あしなみをそろえる
...

足並みを揃える	5540	45.2%
足並みをそろえる	4939	40.3%
足並みが揃う	1060	8.6%
足並みがそろう	722	5.9%

I liked the "same page" example here:

Four days were required to get government departments on the same page; another two weeks to persuade Congress it had no choice but to act.
政府当局の足並みが揃うのに4日掛かった。行動以外の選択肢は無いと議会を説得するのにさらに2週間掛かった。

ASEANは南シナ海問題への対応で足並みがそろわない状態が続く。
