"sequences" are separate objects used to generated, guess what,
sequential numbers. The actual usage of the numbers is undefined.

Auto-inc is auto-inc. Plain and simple. It's something related to
a column in a particular table. Each table can have it's own
"instance" of 1 (and only 1) auto-incrementing column.

Short answer: no.
