Dr. Nick: This is a scene that often gets brought up in a context that mildly grinds my gears. Yes, Evangelions are different from other mechs in that the creators wanted to be cute and didn't assign any one canon height stat to them, instead opting for a rule of cool sliding scale of 40-200 meters I believe (for source, you would need to dig through some old Super Robot Wars games). Sometimes the Evas tower over the buildings of Tokyo-3, whereas in here Asuka needs to climb up one. But besides the Gainax boys saying the quiet part aloud, this actually isn't some sort of crafty genre subversion - despite what the stats might claim, all conventionally animated robot shows run on rule of cool, and if you wish to ruin your fun and start looking for inconsistencies, you're going to find them. Let's take Char's Counterattack as an example: it's a high-budget, comparatively realistic theatrical Gundam film, so you'd think the robots would be animated pretty consistently, but go ahead and pay really close attention to the Sazabi and its ball cockpit. You won't be able to unsee it.
Interestingly enough, while 3D animation obviously does away with a lot of the scaling issues of the old, the really good CG mecha animators know that sometimes you need to cheat and use intentionally off-model assets to create those dynamic shots, as memorably shown in the behind-the-scenes segments of Fafner Exodus.
