The key is really that it could mean different things for different providers, although I would agree that the gist is that the location is enabled to look and feel like a POP without the provider installing the full complement of requisite hardware. A provider I worked at in the past, for example, defined a virtual POP as a non-POP location at which POP pricing was offered - the actual method of delivery there being both irrelevant to it being defined that way and unimportant to the concept as a whole. It let the company be price-competitive with others that may have made more extensive investments in hardware at higher-demand locations, and it was purely based on a business justification. There was no specific technical definition (although in reality we were transparent with our customers about methodology anyway) - this contrasts with other providers that are clearly using it in a way that does define a technical approach. It's just an approach specific to that provider.

The classic example was extending a PRI for dialup modems inside a particular local calling area via a point-to-point T1 back to your modem bank somewhere else that would have been a long distance call for those customers. If you put a modem bank in their local calling area, it's a POP. If you extend the circuit from their local calling area back to your modem bank elsewhere, it's a virtual POP. Modern examples of virtual POPs are much fancier but it's the same basic idea.1. Is virtual POP basically a L2VPN?It can be. Depends on what service you're extending from the "virtual" location.2. Do such vPOP have guaranteed latency/bandwidth?Depends on what you're extending and how.3. Is that really useful?It can be. It can let you dip your toes in a market without a large up-front investment in equipment and backhaul.
