Not exactly a stylistic difference but there are real differences in the dialects. Here's example from many moons ago: "Even I think that's a bad idea." That was an Indian colleague. It took me weeks to figure out that he was using "even" in place of "also."
In a like vein when Australians say "goodeye" they usually aren't talking about your vision.
Or perhaps it was meant to specify that they, themselves, might have been presumed to be an outlier who would think it was a good idea, but who has in fact come to think that is a bad idea.
Examples of this kind of counter-presumptive use of the word "even":
1: On animals and the weather: "It was so cold that even polar bears were suffering from frostbite and frozen digits."
2: On politics, where one's general stance is well-known and who who might be rationally presumed to be a supporter of a particular thing: "Even I think that this issue is a total non-starter."
Even if they may have meant something else, that doesn't mean that they didn't intend for the words to be taken non-literally.
In this case it was indeed "also." I've heard it used that way many times.
Another common phrase in Indian English is "do the needful," which is a delightful formulation. Grammarly has a plausible description of how it arose. [0]
