I doubt it, and I think there is a misunderstanding about the investors Apple referred to in their public statement on the split. As a company's share price rises the stock becomes less liquid, because trades happen in smaller quantities; Berkshire Hathaway's class A shares are probably the most extreme example. Low liquidity is a problem for mutual funds, which have to sell assets whenever an investors sells their shares in the fund (which may be a relatively small sale e.g. a retirement account distribution), because low liquidity makes asset sales more difficult. In general institutional investors will have liquidity rules that constrain the assets their funds can hold to avoid that kind of problem.

Given how much investment capital is held by institutional investors, companies have a good reason to split their shares if the share price is too high. Berkshire Hathaway created a new share class to support the needs of institutional investors, and I would read "accessible to investors" as "conforming to the liquidity requirements of institutional investors."
