I think USCIS is trying to fix one common misuse by certain applicants where he /she applies for H1B through more than one employers ( typically body shop companies) and tries to increase his\her odds of getting the visa. Sometimes the applicant gets more than one H1B visa and wasting the limited visas.

No, this is totally allowed. If you can get more than one legit offer, you can apply more than once.

What isn't allowed is the same company applying for you through multiple subsidiaries or contracting agencies.

You can get one chance per applicant now. So if 10 companies apply for you, the chance of being selected is the same as if only 1 company apply for you.
